Struct DescriptorPool 

pub struct DescriptorPool { /* private fields */ }

A native protobuf descriptor pool.

Built from a prost_types::FileDescriptorSet via DescriptorPool::from_file_descriptor_set. Cheaply cloneable (it wraps an Arc).

Implementations

impl DescriptorPool

pub fn from_file_descriptor_set( fds: FileDescriptorSet, ) -> Result<Self, ReflectError>

Build a pool from a decoded FileDescriptorSet.

Errors

Returns ReflectError::Pool if a descriptor is malformed (missing required name/number fields) or if a field, method input, or method output references a type name that is not present in the set.

pub fn get_message_by_name(&self, full_name: &str) -> Option<MessageDescriptor>

Look up a message by its fully-qualified name (no leading dot).

pub fn get_enum_by_name(&self, full_name: &str) -> Option<EnumDescriptor>

Look up an enum by its fully-qualified name (no leading dot).

pub fn get_service_by_name(&self, full_name: &str) -> Option<ServiceDescriptor>

Look up a service by its fully-qualified name (no leading dot).

pub fn all_messages( &self, ) -> impl ExactSizeIterator<Item = MessageDescriptor> + '_

Iterate over every message in the pool (including nested messages and synthetic map-entry types), in registration order.

pub fn all_enums(&self) -> impl ExactSizeIterator<Item = EnumDescriptor> + '_

Iterate over every enum in the pool, in registration order.

pub fn services(&self) -> impl ExactSizeIterator<Item = ServiceDescriptor> + '_

Iterate over every service in the pool, in registration order.
