Struct Builder 

pub struct Builder { /* private fields */ }

Builder for configuring and running the validation code generator.

Implementations

impl Builder

pub fn new() -> Self

Create a new builder with default settings.

pub fn file_descriptor_set_bytes(self, bytes: Vec<u8>) -> Self

Set the file descriptor set bytes directly.

pub fn file_descriptor_set_path( self, path: impl AsRef<Path>, ) -> Result<Self, Error>

Read the file descriptor set from a file path.

Errors

Returns an error if the file cannot be read.

pub fn out_dir(self, path: impl Into<PathBuf>) -> Self

Override the output directory (defaults to OUT_DIR env var).

pub fn extern_path( self, proto_path: impl Into<String>, rust_path: impl Into<String>, ) -> Self

Map a proto package path to a Rust module path.

This is equivalent to prost-build’s extern_path and should match your prost-build configuration.

Example

prost_protovalidate_build::Builder::new()
    .extern_path(".my.package", "::my_crate::my_package");

pub fn compile(self) -> Result<(), Error>

Run the code generator.

Errors

Returns an error if the descriptor set is missing, cannot be parsed, or the output file cannot be written.

Trait Implementations

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
