Crate pbrs

Expand description

Pure-Rust protobuf kernel. Application API matches Google protobuf v4.

Not crates.io protobuf 4.x (upb/C). Not prost. Official protoc --rust_out links against __internal::runtime.

pbrs = { git = "https://github.com/mingley/pure-protobuf" }

Re-exports§

codegen: Generate field-wise typed messages (not DynamicMessage wrappers, not upb).
copy_counts: Bench-only user-space copy counters (SB-13, Phase 0 attribution).
gen_support: Helpers for plugin-generated typed wrappers around DynamicMessage.
gencode: Field-wise generated TestAllTypes + WKT used by the conformance program.
json: Proto3 JSON mapping.
prelude: Prelude for the Protobuf Rust API.
rt: Runtime helpers for generated code. Not a Google upb kernel.
testdata: Hand-written typed messages with the v4 accessor shape.
text: Protocol buffer text format (textproto).

impl_generated_message: Typed message wrapping a DynamicMessage. Used by plugin gencode and the TestAllTypes wrappers the conformance program drives.
impl_typed_message: Trait impls for field-wise generated messages (merge_bytes / write_to / compute_size).
proto: proto! enables Rust struct-init syntax for protobuf messages.

DescriptorOption: One custom option on a file, message, field, enum, or method descriptor.

DynamicMessage

EnumDescriptor
FieldDescriptor
FileDescriptor
Map: Empty is an 8-byte null. Parse appends to a Vec (last-wins). Lookup uses a lazy index.
MapIter
MapMut
MapView
MessageDescriptor
MethodDescriptor
ParseError: An error that happened during parsing.
ProtoBytes: Owned protobuf bytes.
ProtoStr: Shared immutable view of a protobuf string field. May contain invalid UTF-8.
ProtoString: Owned protobuf string. May contain invalid UTF-8 (C++ interop).
Repeated: Empty is an 8-byte null. Box<Vec<_>> so unused TAT collections stay off the struct.
RepeatedIter
RepeatedMut: Mutable proxy of a repeated field.
RepeatedView: View of a repeated field.
SerializeError: An error that happened during serialization.
ServiceDescriptor
UnknownEnumValue: An integer value wasn’t known for an enum while converting.
UnknownFields
Utf8Error: The bytes were not valid UTF-8.

RECURSION_LIMIT: Maximum nesting depth for binary, JSON, and text parse. A payload nested more than this many messages returns ParseError.

AsMut
AsView
Clear
ClearAndParse
CopyFrom
Enum: Implemented by generated enum types.
IntoMut
IntoProxied: A value-to-Proxied conversion that consumes the input.
IntoView
MapKey: Types allowed as map keys.
MapValue: Types allowed as map values.
MergeFrom
Message: A trait that all owned message types implement.
MessageMut: A trait that all message muts implement.
MessageName: The protobuf full name of a generated message (package.Message).
MessageType: Marker implemented only by message types.
MessageView: A trait that all message views implement.
MutProxied: A type that can be accessed through a mutable proxy.
Parse: Operations related to constructing a message.
ProtoPut: Used by proto! list/map literals so a field mutator can take either a repeated element or a map key/value pair.
Proxied: A type that can be accessed through a reference-like proxy.
Serialize: Operations related to reading a message.
Singular: Types allowed as a simple field, repeated element, or map value.
TakeFrom
WireOut: Byte sink for binary encode. Implemented for every BufMut (Vec<u8>, BytesMut, tonic EncodeBuf).

message_eq: Message equality which may have false-negatives in the face of unknown fields.
