Struct AsyncMemReader 

pub struct AsyncMemReader { /* private fields */ }

A cloneable, read-only in-memory positioned source for tests and examples.

Implementations

impl AsyncMemReader

pub fn from_bytes(data: Vec<u8>) -> Self

Construct a reader from owned bytes.

pub fn new() -> Self

Construct an empty reader.

pub fn as_bytes(&self) -> &[u8]

Borrow the complete source contents.

pub fn into_bytes(self) -> Vec<u8>

Consume the reader and return its source contents.
