Struct Transaction 

pub struct Transaction { /* private fields */ }

Edits against one version, in order, none overlapping another.

Transaction::new is the one construction point, so edits out of order are refused once rather than read two ways.

Implementations

impl Transaction

pub fn new(baseline: B3Hash, edits: Vec<Edit>) -> Result<Transaction, AxError>

Edits made on the version baseline.

Two insertions at one offset are kept in the order given; any other pair must not share a byte.

Errors

E_INVALID_ARGS naming the first edit that starts before the one ahead of it ends.

pub fn baseline(&self) -> B3Hash

The version these edits were made on.

pub fn edits(&self) -> &[Edit]

pub fn apply(&self, source: &[u8]) -> Result<Applied, AxError>

Applies the edits to source, which must be the baseline version.

Errors

E_VERSION_CONFLICT when source is not the baseline: somebody saved since these edits were made, and their change stands. E_INVALID_ARGS when an edit reaches past the end of source. Either way nothing was applied.
