Struct ErasureCodeBuilder 

pub struct ErasureCodeBuilder { /* private fields */ }

The ErasureCodeBuilder is used to build the ErasureCode struct.

It is a builder pattern that allows you to set the parameters of the erasure code.

Implementations

impl ErasureCodeBuilder

pub fn new() -> Self

Create a new ErasureCodeBuilder instance. With default values:

• k and m are not set
• w is CodeWord::W8
• packet_size is not set
• tech is not set
• coding_method is not set

pub fn k(self, k: NonZeroI32) -> Self

Set the number of data devices.

pub fn m(self, m: NonZeroI32) -> Self

Set the number of parity devices.

pub fn w(self, w: CodeWord) -> Self

Set the code word size.

Default

• CodeWord::W8

Requires

• $k + m <= 2^w$

pub fn packet_size(self, packet_size: NonZeroI32) -> Self

Set the packet size.

Requires

• packet_size must be a multiple of the machine long size

pub fn tech(self, tech: Technique) -> Self

Set the implementation technique.

pub fn coding_method(self, method: CodingMethod) -> Self

Set the coding method.

pub fn build(self) -> Result<ErasureCode, Error>

Build the ErasureCode struct.
