Struct S3ExpressSessionProvider 

pub struct S3ExpressSessionProvider { /* private fields */ }

S3 Express One Zone session provider that creates session credentials.

This provider implements the CreateSession API for S3 Express One Zone buckets, which provides low-latency access through temporary session-based credentials.

Important

• The session token returned by this provider should be used with the x-amz-s3session-token header instead of the standard x-amz-security-token header when making requests to S3 Express One Zone buckets.
• This provider does not cache sessions internally. The upper layer (e.g., Signer) handles credential caching and will request new sessions when they expire.

Example

use reqsign_aws_v4::{S3ExpressSessionProvider, DefaultCredentialProvider};
use reqsign_core::ProvideCredential;

let provider = S3ExpressSessionProvider::new(
    "my-bucket--usw2-az1--x-s3",
    DefaultCredentialProvider::new(),
);

// Each call to provide_credential creates a new session

Implementations

impl S3ExpressSessionProvider

pub fn new( bucket: impl Into<String>, provider: impl ProvideCredential<Credential = Credential> + 'static, ) -> Self

Create a new S3 Express session provider for a specific bucket.

Arguments

• bucket - The S3 Express One Zone bucket name (e.g., “my-bucket–usw2-az1–x-s3”)
• provider - The base credential provider to use for CreateSession API calls
