Default AWS Credential Provider Chain
Resolution order:
- Environment variables:
EnvironmentVariableCredentialsProvider - Shared config (
~/.aws/config,~/.aws/credentials):SharedConfigCredentialsProvider - Web Identity Tokens
- ECS (IAM Roles for Tasks) & General HTTP credentials:
ecs - EC2 IMDSv2
The outer provider is wrapped in a refreshing cache.
More providers are a work in progress.
§Examples
Create a default chain with a custom region:
use aws_types::region::Region;
use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder()
.region(Region::new("us-west-1"))
.build();Create a default chain with no overrides:
use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder().build();Create a default chain that uses a different profile:
use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder()
.profile_name("otherprofile")
.build();Implementations§

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
