Struct IoSlices 

pub struct IoSlices<'a> {
    pub slots: Vec<SliceSlot<'a>>,
}

A collection of vectored I/O slices used for efficient streaming writes.

Internally maintains a list of SliceSlots, which can be borrowed or owned. Provides utilities to build and write the combined data.

Fields

slots: Vec<SliceSlot<'a>>

Internal list of slices to be written.

Implementations

impl<'a> IoSlices<'a>

pub fn add_slice(&mut self, buf: &'a [u8])

Adds a borrowed slice to the buffer.

Arguments

• buf – A borrowed slice (&[u8]) to be written.

pub fn add_buffered(&mut self, buf: Vec<u8>)

Adds an owned buffer to the buffer list.

Arguments

• buf – A Vec<u8> to be owned and written.

pub fn get(&self) -> Vec<IoSlice<'_>>

Converts all internal slots into a Vec<IoSlice> for writing.

This method is non-destructive and safe to call multiple times.

Returns

A vector of std::io::IoSlice values ready for write_vectored.

pub fn append(&mut self, another: IoSlices<'a>)

Appends another IoSlices into this one, consuming the other buffer.

Arguments

• another – Another IoSlices instance to merge into this one.

pub fn write_vectored_all<T: Write>(&self, buf: &mut T) -> Result<()>

Writes all buffers to the given stream using vectored I/O.

Handles partial writes and retries until all slices are written.

Arguments

• buf – A writable output stream.

Errors

Returns an error if the write operation fails or stalls (WriteZero).

Trait Implementations

impl<'a> Default for IoSlices<'a>

fn default() -> IoSlices<'a>

Returns the “default value” for a type.
