Trait Destination 

Source 
pub trait Destination: Write + Sealed {
    // Required methods
    fn can_patch(&self) -> bool;
    fn position(&mut self, relative: u64) -> Result<()>;
}
Expand description

Writer access derived by wrapping an actual writer in Forward or SeekBack. Sealed so callers cannot invent seek support independently of the writer.

Required Methods§

Source

fn can_patch(&self) -> bool

Whether this destination can overwrite relative output positions.

Source

fn position(&mut self, relative: u64) -> Result<()>

Seek relative to the output origin; fails for a forward-only writer.

Dyn Compatibility§

This trait is dyn compatible.

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