Struct JsonCodecSettingsBuilder 

pub struct JsonCodecSettingsBuilder { /* private fields */ }

Builder for JsonCodecSettings.

Implementations

impl JsonCodecSettingsBuilder

pub fn enforce_strictness(self, value: bool) -> Self

Enforces JSON grammar and request document validity. Disabled by default.

pub fn validate_skipped_values(self, value: bool) -> Self

Whether discarded string contents are validated. Enabled by default.

When enabled, escape syntax is checked without decoding Unicode escapes. enforce_strictness applies only to values read. When disabled, strings and keys inside discarded objects are scanned without decoding or validating escapes. Container syntax, number/literal grammar, truncation, and depth limits are still checked. Values actually read are unaffected.

pub fn validate_skipped_string_encoding(self, value: bool) -> Self

Checks discarded strings for UTF-8 and unescaped control characters without decoding or validating their escape sequences. Disabled by default.

pub fn allow_integral_float_numbers(self, value: bool) -> Self

Accepts exactly integral decimal/exponent numbers for integer members. Disabled by default; ordinary integer spellings retain exact parsing.

pub fn allow_leading_zeros(self, value: bool) -> Self

Permits leading zeros in JSON numbers even with enforce_strictness(true). Disabled by default. This matches the legacy JSON parser without relaxing other grammar checks. Applies to read and skipped numbers alike.

pub fn allow_trailing_decimal_point(self, value: bool) -> Self

Permits an empty fraction after a decimal point, such as 12. or 12.e2, even with enforce_strictness(true). Disabled by default. Integer members additionally require allow_integral_float_numbers(true) and a whole value. Applies to read and skipped numbers alike.

pub fn allow_empty_integer_part(self, value: bool) -> Self

Permits negative fractions with no integer digits, such as -.123 or -.123e2, even with enforce_strictness(true). Disabled by default. Under strict number validation, .123, -., and -.e2 remain invalid. Applies to read and skipped numbers alike.

pub fn use_json_name(self, value: bool) -> Self

Whether to use the @jsonName trait for member names.

pub fn default_timestamp_format(self, value: TimestampFormat) -> Self

Default timestamp format when not specified by @timestampFormat trait.

pub fn max_depth(self, value: u32) -> Self

Sets the maximum aggregate nesting depth the deserializer will accept before returning an error. Defaults to 128.

pub fn strict_timestamp_formats(self, value: bool) -> Self

Require timestamps to use exactly the wire form their resolved format prescribes: a JSON number for epoch-seconds, an RFC 3339 string without a UTC offset for date-time, an IMF-fixdate string for http-date. Off by default; when enabled, any other form is rejected.

pub fn dispatch_null_members(self, value: bool) -> Self

Pass null structure members to the consumer. Defaults to false, preserving existing codec callers; schema server readers decide how each null affects their builders.

pub fn protocol_id(self, value: ShapeId<'static>) -> Self

Sets the protocol id surfaced in DocumentSettings diagnostics. Defaults to aws.smithy.json#JsonCodec. AWS protocols (awsJson1_0, awsJson1_1, restJson1) supply their own shape id so coercion errors point at the originating protocol.

pub fn use_string_for_arbitrary_precision(self, value: bool) -> Self

Configures whether bigInteger and bigDecimal shapes serialize as JSON strings (when true) or as raw JSON numbers (when false, the default).

This is schema-driven: a Document carries no schema and has no arbitrary-precision variant, so write_document is unaffected.

Set to true for interop with receivers using f64-routed JSON parsers that would otherwise lose precision on large integers or decimals. The read path always accepts both forms.

pub fn normalize_arbitrary_precision(self, value: bool) -> Self

Rewrites arbitrary-precision text that is a decimal but not a JSON number (+007, .5, 1.) to the equivalent JSON number instead of rejecting it. Defaults to false, so existing callers keep rejecting it; AWS servers set it to true, matching their lenient handling of such numbers on the read path (allow_leading_zeros, allow_trailing_decimal_point).

pub fn default_namespace(self, namespace: impl Into<String>) -> Self

Sets the default Smithy namespace used to resolve relative shape IDs in JSON __type discriminator fields. When set, a relative __type: "Capacity" is lifted to <namespace>#Capacity on the resulting DiscriminatedDocument. Absolute __type values (already containing #) are taken as-is regardless.

Defaults to None — relative names are not lifted.

pub fn build(self) -> JsonCodecSettings

Builds the settings.
