pub struct Utf8Chunk<'a> { /* private fields */ }
Expand description
An item returned by the Utf8Chunks
iterator.
A Utf8Chunk
stores a sequence of u8
up to the first broken character
when decoding a UTF-8 string.
§Examples
Implementations§
source§impl<'a> Utf8Chunk<'a>
impl<'a> Utf8Chunk<'a>
1.79.0 · sourcepub fn valid(&self) -> &'a str
pub fn valid(&self) -> &'a str
Returns the next validated UTF-8 substring.
This substring can be empty at the start of the string or between broken UTF-8 characters.
1.79.0 · sourcepub fn invalid(&self) -> &'a [u8]
pub fn invalid(&self) -> &'a [u8]
Returns the invalid sequence that caused a failure.
The returned slice will have a maximum length of 3 and starts after the
substring given by valid
. Decoding will resume after this sequence.
If empty, this is the last chunk in the string. If non-empty, an unexpected byte was encountered or the end of the input was reached unexpectedly.
Lossy decoding would replace this sequence with U+FFFD REPLACEMENT CHARACTER
.
