Trait Seek

pub trait Seek: ErrorType {
    // Required method
    async fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>;

    // Provided methods
    async fn rewind(&mut self) -> Result<(), Self::Error> { ... }
    async fn stream_position(&mut self) -> Result<u64, Self::Error> { ... }
}

Async seek within streams.

This trait is the embedded-io-async equivalent of [std::io::Seek].

Required Methods

async fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>

Seek to an offset, in bytes, in a stream.

Provided Methods

async fn rewind(&mut self) -> Result<(), Self::Error>

Rewind to the beginning of a stream.

async fn stream_position(&mut self) -> Result<u64, Self::Error>

Returns the current seek position from the start of the stream.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
