Expand description
Reader
which consumes an input byte slice.
Implementations
sourceimpl<'a> SliceReader<'a>
impl<'a> SliceReader<'a>
sourcepub fn new(bytes: &'a [u8]) -> Result<Self>
pub fn new(bytes: &'a [u8]) -> Result<Self>
Create a new slice reader for the given byte slice.
sourcepub fn error(&mut self, kind: ErrorKind) -> Error
pub fn error(&mut self, kind: ErrorKind) -> Error
Return an error with the given ErrorKind
, annotating it with
context about where the error occurred.
sourcepub fn value_error(&mut self, tag: Tag) -> Error
pub fn value_error(&mut self, tag: Tag) -> Error
Return an error for an invalid value with the given tag.
