Struct DigestBuilder 

pub struct DigestBuilder { /* private fields */ }

Incremental digest builder for computing digests over multiple fields.

Use this when the digest domain spans multiple fields and you want to hash them incrementally without allocating a single concatenated buffer.

Implementations

impl DigestBuilder

pub fn new() -> Self

Create a new builder.

pub fn update(&mut self, data: &[u8]) -> &mut Self

Feed raw bytes into the digest.

pub fn update_str(&mut self, data: &str) -> &mut Self

Feed a UTF-8 string into the digest.

pub fn separator(&mut self) -> &mut Self

Feed a field separator. Use between fields to prevent ambiguity.

pub fn update_json<T: Serialize + ?Sized>( &mut self, value: &T, ) -> Result<&mut Self, DigestError>

Feed a JSON-serializable value using canonical serialization.

pub fn finalize(self) -> ContentDigest

Finalize and return the digest.

Trait Implementations

impl Default for DigestBuilder

fn default() -> Self

Returns the “default value” for a type.
