Struct SGEntry

Source 
pub struct SGEntry(/* private fields */);
Expand description

A single entry in a scatter-gather list.

An SGEntry represents a single, physically contiguous segment of memory that has been mapped for DMA.

Instances of this struct are obtained by iterating over an SGTable. Drivers do not create or own SGEntry objects directly.

Implementations§

Source§

impl SGEntry

Source

pub fn dma_address(&self) -> DmaAddress

Returns the DMA address of this SG entry.

This is the address that the device should use to access the memory segment.

Source

pub fn dma_len(&self) -> ResourceSize

Returns the length of this SG entry in bytes.
