Struct StreamingPeekableIterState 

pub struct StreamingPeekableIterState<T> { /* private fields */ }

State for StreamingPeekableIter implementations.

Implementations

impl<T> StreamingPeekableIterState<T>

pub fn peek_buffer_replace_and_truncate( &mut self, position: usize, replace_with: u8, )

Modify the peek buffer, overwriting the byte at position with the given byte to replace_with while truncating it to contain only bytes until the newly replaced position.

This is useful if you would want to remove ‘special bytes’ hidden behind, say a NULL byte to disappear and allow standard line readers to read the next line as usual.

Note that position does not include the 4 bytes prefix (they are invisible outside the reader)

pub fn stopped_at(&self) -> Option<PacketLineRef<'static>>

Returns the packet line that stopped the iteration, or None if the end wasn’t reached yet, on EOF, or if fail_on_err_lines() was true.

pub fn reset(&mut self)

Reset all iteration state allowing to continue a stopped iteration that is not yet at EOF.

This can happen once a delimiter is reached.

pub fn reset_with(&mut self, delimiters: &'static [PacketLineRef<'static>])

Similar to reset() with support to changing the delimiters.

pub fn fail_on_err_lines(&mut self, value: bool)

If value is true the provider will check for special ERR packet lines and stop iteration when one is encountered.

Use [stopped_at()]StreamingPeekableIterState::stopped_at() to inspect the cause of the end of the iteration. ne

pub fn replace(&mut self, read: T) -> T

Replace the reader used with the given read, resetting all other iteration state as well.
