Enum Sha256Policy

Source

pub enum Sha256Policy {
    Compute,
    Provided(Sha256),
    Skip,
}

Expand description

Controls how SHA-256 is handled during file cleaning.

Variants§

§

Compute

Compute SHA-256 from the file data.

§

Provided(Sha256)

Use a pre-computed SHA-256 value.

§

Skip

Skip SHA-256 entirely; no metadata_ext is written to the shard.

Implementations§

Source §

impl Sha256Policy

Source

pub fn from_skip(skip: bool) -> Self

Returns Skip when true, Compute when false.

Source

pub fn from_hex(hex: &str) -> Self

Parses a hex-encoded SHA-256 string into a policy.

Returns Provided(hash) if the hex is valid, Compute otherwise.
