pub trait FileSource: Send + Sync {
// Required method
fn open(&self) -> Result<SourceReader>;
}Expand description
A provider of virtual file contents.
Each call to FileSource::open must create a fresh,
independent reader positioned at the beginning of the
file.
A receiving application may request the contents of the same virtual file multiple times or concurrently.
Implementations must be safe to share across threads.
Required Methods§
Sourcefn open(&self) -> Result<SourceReader>
fn open(&self) -> Result<SourceReader>
Opens a new reader for this file’s contents.
The returned reader must not depend on the position of readers returned by earlier calls.
§Errors
Returns an I/O error if the contents cannot be opened or prepared.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
