Struct pliantdb_core::document::Revision[][src]

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

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

impl Revision[src]

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

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

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

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

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

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

Panics

Panics if id overflows.
