PROST version 0.13.0
PROST! is a Protocol Buffers implementation for the Rust Language.
prost
generates simple, idiomatic Rust code fromproto2
andproto3
files.This major update brings new features and fixes:
Breaking changes
derive Copy trait for messages where possible (feat: derive Copy trait for messages where possible #950)
prost-build
will automatically derivetrait Copy
for some messages. If you manually implementCopy
you should remove your implementation.Change generated functions signatures to remove type parameters (Change generated functions signatures to remove type parameters #1045)
The function signature of
trait Message
is changed to useimpl Buf
instead of a named generic type. If you implementtrait Message
, you should change the function signature.Lightweight error value in TryFrom for enums (A more lightweight, informative error value in
TryFrom<i32>
for enums #1010)When a
impl TryFrom<i32>
is generated byprost
derive macros, it will now return the error typeUnknownEnumValue
instead ofDecodeError
. The new error can be used to retreive the integer value that failed to convert.Features
fix: Only touch include file if contents is changed (fix: Only touch include file if contents is changed #1058)
Most generated files are untouched when the contents doesn't change. Use the same mechanism for include file as well.
