[+] Show declaration

pub struct Session(_);

[−] Expand description

Represents an erasure “session” with a particular configuration and number of data and coding shreds

Implementations

impl Session[−]

pub fn new(data_count: usize, coding_count: usize) -> Result<Session, Error>

pub fn new_from_config(config: &ErasureConfig) -> Result<Session, Error>

pub fn encode(
    &self,
    data: &[&[u8]],
    parity: &mut [&mut [u8]]
) -> Result<(), Error>[−]

Create coding blocks by overwriting parity

pub fn decode_blocks(
    &self,
    blocks: &mut [(&mut [u8], bool)]
) -> Result<(), Error>[−]

Recover data + coding blocks into data blocks

Arguments

• data - array of data blocks to recover into
• coding - array of coding blocks
• erasures - list of indices in data where blocks should be recovered
