Struct RequestSigner 

pub struct RequestSigner { /* private fields */ }

Available on crate feature services-s3 only.

RequestSigner that implement AWS SigV4.

• Signature Version 4 signing process

Implementations

impl RequestSigner

pub fn new(service: &str, region: &str) -> RequestSigner

Create a new builder for AWS V4 signer.

pub fn with_standard_session_token(self) -> RequestSigner

Use the standard AWS session-token representation.

This mode is required when an S3 Express request is authenticated with temporary IAM or STS credentials. Header authentication uses x-amz-security-token, and query authentication uses X-Amz-Security-Token.

By default, S3 Express endpoints use the CreateSession credential representation: x-amz-s3session-token for header authentication and X-Amz-S3session-Token for query authentication. The S3 Express CopyObject, HeadBucket, and UploadPartCopy operations require IAM credentials instead of CreateSession credentials.

This setting only selects how an existing Credential session token is represented. It does not modify the credential or load a different credential source.

Example

use reqsign_aws_v4::RequestSigner;

let signer = RequestSigner::new("s3express", "us-west-2")
    .with_standard_session_token();
