Struct OperationCatalog 

pub struct OperationCatalog { /* private fields */ }

The operations offered to a turn, by key. A duplicate key is refused, never shadowed.

Implementations

impl OperationCatalog

pub fn new( operations: impl IntoIterator<Item = OperationSpec>, ) -> Result<Self, ReductionError>

A catalog of operations.

Errors

crate::error::ReductionError::DuplicateOperation for a key offered twice.

pub fn insert(&mut self, spec: OperationSpec) -> Result<(), ReductionError>

Adds an operation.

Errors

crate::error::ReductionError::DuplicateOperation when its key is taken.

pub fn get(&self, key: &OperationKey) -> Option<&OperationSpec>

The operation with this key.

pub fn iter(&self) -> impl Iterator<Item = &OperationSpec>

Every operation, in the order added.

pub fn len(&self) -> usize

How many there are.

pub fn is_empty(&self) -> bool

Whether there are none.
