Trait Source 

pub trait Source: Send + Sync {
    // Required methods
    fn len(&self) -> u64;
    fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn as_bytes(&self) -> Option<&[u8]> { ... }
}

Random access to the bytes of an archive.

Required Methods

fn len(&self) -> u64

Total length in bytes.

fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>

Fills buf from offset; fails if the range is out of bounds.

Provided Methods

fn is_empty(&self) -> bool

fn as_bytes(&self) -> Option<&[u8]>

The whole content when it already sits in memory, so reads can borrow it.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
