Struct FileTransaction 

pub struct FileTransaction { /* private fields */ }

An all-or-nothing set of file and directory mutations.

Implementations

impl FileTransaction

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn mutations(&self) -> &[FileMutation]

pub fn plan_write( &mut self, path: impl Into<PathBuf>, replacement: impl Into<Vec<u8>>, ) -> Result<bool, RunnerIoError>

pub fn plan_remove( &mut self, path: impl Into<PathBuf>, ) -> Result<bool, RunnerIoError>

pub fn plan_create_directory( &mut self, path: impl Into<PathBuf>, ) -> Result<bool, RunnerIoError>

pub fn plan_remove_empty_directory(&mut self, path: impl Into<PathBuf>)

pub fn extend(&mut self, other: FileTransaction) -> Result<(), RunnerIoError>

pub fn commit(&self) -> Result<bool, RunnerIoError>

Verifies every before-state and applies the complete mutation set.

If a directory creation, write, or removal fails, already-applied mutations are rolled back.
