Expand description

A builder for a work queue entry.

Implementations§

Source§

impl<'a> WqeBuilder<'a>

Source

pub fn set_client_oob_in_sgl(&mut self, last_vbytes: u8)

Sets that client out-of-band data is provided in the first scatter-gather entry, with the specified last_vbytes value.

Source

pub fn set_gd_client_unit_data(&mut self, value: u16)

Sets the gd_client_unit_data field in the header.

Source

pub fn push_sge(&mut self, sge: Sge)

Appends a scatter-gather entry to the work queue entry.

Source

pub fn sge_count(&self) -> u8

Returns the number of scatter-gather entries added so far.

Source

pub fn finish(self) -> Result<u32, QueueFull>

Finishes building the work queue entry and writes it to the queue, updating the tail and returning the total length of the entry.

Call Wq::commit to notify the device of the new entry.
