Source 
pub trait Source {
    // Required method
    fn fetch(&self, url: &str, output: &mut dyn Write, limit: u64) -> Result<()>;

    // Provided method
    fn fetch_from(
        &self,
        url: &str,
        output: &mut dyn Write,
        offset: u64,
        limit: u64,
    ) -> Result<Transfer> { ... }
}
Expand description

Transport boundary shared by the CLI and deterministic tests. Implementations must refuse oversized responses. Sources are required to honor the supplied URL exactly.

Required Methods§

Source

fn fetch(&self, url: &str, output: &mut dyn Write, limit: u64) -> Result<()>

Provided Methods§

Source

fn fetch_from( &self, url: &str, output: &mut dyn Write, offset: u64, limit: u64, ) -> Result<Transfer>

Append bytes beginning at offset, within the remaining byte budget. Restart must write nothing. Errors may leave a prefix; only a final whole-file hash proves it. Sources without range support safely restart that file.

Dyn Compatibility§

This trait is dyn compatible.

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