Trait kdevice::block::BlockBus[−][src]

pub trait BlockBus {
    fn probe(&mut self) -> Result<()>;
    fn read(&mut self, bno: usize, buf: &mut [u8]) -> Result<()>;
    fn write(&mut self, bno: usize, buf: &[u8]) -> Result<()>;
}

Expand description

Block device trait that you need to implement for each slot.

For each instance, all three methods are guaranteed to becalled exlusively.

Required methods

`fn probe(&mut self) -> Result<()>`[src]

Return Ok if the bus is active.

`fn read(&mut self, bno: usize, buf: &mut [u8]) -> Result<()>`[src]

Read a block from the block device.

`fn write(&mut self, bno: usize, buf: &[u8]) -> Result<()>`[src]

Write a block to the block device.
