Struct aws_smithy_checksums::body::validate::ChecksumBody

source · 
pub struct ChecksumBody<InnerBody> { /* private fields */ }
Expand description

A body-wrapper that will calculate the InnerBody’s checksum and emit an error if it doesn’t match the precalculated checksum.

Implementations§

impl ChecksumBody<SdkBody>

source

pub fn new( body: SdkBody, checksum: Box<dyn HttpChecksum>, precalculated_checksum: Bytes, ) -> Self
