Trait SectorDevice 

pub trait SectorDevice {
    // Required method
    fn read_sector(&self, sector: u64, buf: &mut [u8; 512]) -> Result<(), ()>;
}

Sector device trait for reading 512-byte sectors.

This is used for variable block size support, where the filesystem block size may be larger than 512 bytes. The reader will read multiple sectors to assemble a full block.

Required Methods

fn read_sector(&self, sector: u64, buf: &mut [u8; 512]) -> Result<(), ()>

Read a single 512-byte sector.

Arguments

• sector - Sector number to read
• buf - Buffer to read into (must be exactly 512 bytes)

Returns

Ok(()) on success, Err(()) on failure.

Implementors

impl<T: BlockDevice> SectorDevice for T

Blanket implementation: any BlockDevice is also a SectorDevice.
