Enum DynFileSource

pub enum DynFileSource {
    FileReader(FileReader),
    FileSource(FileSource),
    Dead,
}

A runtime adapter of FileReader and FileSource, also able to switch between the two mode of operations dynamically.

Variants

FileReader(FileReader)

FileSource(FileSource)

Dead

If you encounter this, it’s a programming mistake

Implementations

impl DynFileSource

pub async fn new( file_id: FileId, stype: FileSourceType, ) -> Result<Self, FileErr>

pub async fn seek(&mut self, to: SeqPos) -> Result<u64, FileErr>

pub fn source_type(&self) -> FileSourceType

pub async fn switch_to(self, stype: FileSourceType) -> Result<Self, FileErr>

Switch to a different mode of operation.

Warning: This future must not be canceled.

pub async fn end(self) -> AsyncFile

pub fn offset(&self) -> u64

pub fn file_size(&self) -> u64

pub fn is_dead(&self) -> bool
