Struct DescriptorTable 

pub struct DescriptorTable {
    descriptors: Vec<&'static FieldDescriptor>,
    index: FastMap<&'static str, FastMap<&'static str, DescriptorId>>,
}

Indexed collection of all FieldDescriptors registered via inventory.

Fields

descriptors: Vec<&'static FieldDescriptor>

index: FastMap<&'static str, FastMap<&'static str, DescriptorId>>

Implementations

impl DescriptorTable

pub fn build() -> Self

Collect all registered descriptors and build the lookup table.

Panics

Panics if more than u16::MAX descriptors are registered.

pub fn len(&self) -> usize

Returns the number of registered descriptors.

pub fn is_empty(&self) -> bool

Returns whether no descriptors are registered.

pub fn iter(&self) -> DescriptorIter<'_>

Iterate all descriptors with their IDs.

pub(crate) fn lookup( &self, domain: &str, name: &str, ) -> Option<(DescriptorId, &FieldDescriptor)>

pub(crate) fn get(&self, id: DescriptorId) -> Option<&FieldDescriptor>
