S3ExpressSessionProvider

opendal::services::reqsign_aws_v4

Struct S3ExpressSessionProvider 

pub struct S3ExpressSessionProvider { /* private fields */ }
Available on crate feature services-s3 only.
Expand description

S3 Express fixed-flow credential provider.

This compatibility API loads its source through ProvideCredential and creates a ReadWrite session on every call. New explicit credential-vending flows should use S3ExpressSessionGranter through reqsign_core::Granter.

Implementations§

§

impl S3ExpressSessionProvider

pub fn new( bucket: impl Into<String>, provider: impl ProvideCredential<Credential = Credential> + 'static, ) -> S3ExpressSessionProvider

Create a fixed ReadWrite session provider for a directory bucket.

The legacy constructor infers the Region from well-known AWS Zone ID prefixes. Use S3ExpressSessionProvider::with_region when the Zone is new or belongs to a Local Zone that the compatibility inference does not recognize.

pub fn with_region(self, region: impl Into<String>) -> S3ExpressSessionProvider

Bind the AWS Region instead of using compatibility inference.
