Struct glommio::io::StreamReader [−][src]
pub struct StreamReader { /* fields omitted */ }
Expand description
Provides linear read access to a BufferedFile
.
The StreamReader
implements AsyncRead
and AsyncBufRead
, which can offer the user with a convenient
way of issuing reads. However note that this mandates a copy between the OS page cache and
an intermediary buffer before it reaches the user-specified buffer
Implementations
Trait Implementations
Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more

into buf
