pub struct Revision {
    pub id: u32,
    pub sha256: [u8; 32],
}
Expand description

Information about a Document’s revision history.

Fields§

§id: u32

The current revision id of the document. This value is sequentially incremented on each document update.

§sha256: [u8; 32]

The SHA256 digest of the bytes contained within the Document.

Implementations§

source§

impl Revision

source

pub fn new(contents: &[u8]) -> Self

Creates the first revision for a document with the SHA256 digest of the passed bytes.

source

pub fn with_id(id: u32, contents: &[u8]) -> Self

Creates a revision with id for a document with the SHA256 digest of the passed bytes.

source

pub fn next_revision(&self, new_contents: &[u8]) -> Option<Self>

Creates the next revision in sequence with an updated digest. If the digest doesn’t change, None is returned.

Panics

Panics if id overflows.
