Struct TargetCatalog 

pub struct TargetCatalog(/* private fields */);

An encoder’s synthesis targets and its optional cross-format default.

The default is a position in targets, validated when the catalog is constructed. A catalog may have no default when the encoder cannot synthesize a document from a source of another format.

Implementations

impl TargetCatalog

pub const fn empty(namespace: &'static str) -> Self

Builds an empty catalog for a dialect-free format.

pub const fn new( targets: &'static [TargetDescriptor], default: Option<usize>, ) -> Self

Builds a nonempty catalog with one namespace and an optional default row.

Panics if rows have different namespaces, a spelling selects multiple rows, or the default is out of bounds.

pub fn namespace(self) -> &'static str

Returns the format namespace owned by this catalog.

pub const fn targets(self) -> &'static [TargetDescriptor]

Returns all synthesis targets in catalog order.

pub const fn is_empty(self) -> bool

Returns whether this catalog has no synthesis targets.

pub const fn len(self) -> usize

Returns the number of synthesis targets.

pub fn iter(self) -> Iter<'static, TargetDescriptor>

Iterates over synthesis targets in catalog order.

pub fn find(self, token: &str) -> Option<(usize, &'static TargetDescriptor)>

Returns the row named by a full id, format-local id, or alias, with its position.

pub fn default(self) -> Option<(usize, &'static TargetDescriptor)>

Returns the cross-format default and its position, when declared.
