Trait mentat::vocabulary::VocabularySource [−] [src]

pub trait VocabularySource {
    fn definitions(&mut self) -> Vec<Definition>;

    fn pre(
        &mut self, 
        _in_progress: &mut InProgress, 
        _checks: &VocabularyStatus
    ) -> Result<()> { ... }
    fn post(&mut self, _in_progress: &mut InProgress) -> Result<()> { ... }
}

Implement VocabularySource to have full programmatic control over how a set of Definitions are checked against and transacted into a store.

Required Methods

Important traits for Vec<u8>

impl Write for Vec<u8>

`fn definitions(&mut self) -> Vec<Definition>`

Called to obtain the list of Definitions to install. This will be called before pre.

Provided Methods

`fn pre( &mut self, _in_progress: &mut InProgress, _checks: &VocabularyStatus ) -> Result<()>`

Called before the supplied Definitions are transacted. Do not commit the InProgress. If this function returns Err, the entire vocabulary operation will fail.

`fn post(&mut self, _in_progress: &mut InProgress) -> Result<()>`

Called after the supplied Definitions are transacted. Do not commit the InProgress. If this function returns Err, the entire vocabulary operation will fail.
