Struct Config 

#[non_exhaustive]
pub struct Config {
    pub credentials: CredentialSource,
    pub endpoint: Option<String>,
    pub region: String,
    pub retry: RetryPolicy,
    pub transfer: TransferConfig,
    /* private fields */
}

Top-level client configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

credentials: CredentialSource

How to obtain AWS credentials.

endpoint: Option<String>

Custom endpoint for S3-compatible backends (MinIO, R2, GCS). When None, uses the default AWS endpoint.

region: String

AWS region (e.g. us-east-1).

retry: RetryPolicy

Retry behaviour.

transfer: TransferConfig

Transfer tuning knobs.

Implementations

impl Config

pub fn endpoint_url(&self) -> &str

Resolved S3 endpoint URL.

pub fn new(region: impl Into<String>, credentials: CredentialSource) -> Self

Create a new config with the given region and credentials.

Uses default transfer and retry settings. Override fields after construction if needed.

pub fn with_endpoint( region: impl Into<String>, credentials: CredentialSource, endpoint: String, ) -> Self

Create a new config with a custom endpoint for S3-compatible backends.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
