Struct Utf8TextReader 

pub struct Utf8TextReader<R> { /* private fields */ }

Streaming text reader for UTF-8 byte input.

Implementations

impl<R> Utf8TextReader<R>

where R: BufRead,

pub const fn new(inner: R) -> Self

Creates a UTF-8 text reader over a buffered byte reader.

Parameters

• inner: Buffered byte reader that yields UTF-8 data.

Returns

A text reader wrapping inner.

pub const fn get_ref(&self) -> &R

Returns a shared reference to the wrapped reader.

Returns

The wrapped reader.

pub fn get_mut(&mut self) -> &mut R

Returns a mutable reference to the wrapped reader.

Returns

The wrapped reader.

pub fn into_inner(self) -> R

Returns the wrapped reader.

Returns

The underlying buffered reader.

impl<R> Utf8TextReader<BufReader<R>>

where R: Read,

pub fn from_read(reader: R) -> Self

Creates a UTF-8 text reader over an unbuffered byte reader.

Parameters

• reader: Byte reader that yields UTF-8 data.

Returns

A text reader wrapping reader in BufReader.
