Struct pbjson_build::Builder

pub struct Builder { /* private fields */ }

Implementations

impl Builder

pub fn new() -> Self

Create a new Builder

pub fn out_dir<P>(&mut self, path: P) -> &mut Selfwhere
    P: Into<PathBuf>,

Configures the output directory where generated Rust files will be written.

If unset, defaults to the OUT_DIR environment variable. OUT_DIR is set by Cargo when executing build scripts, so out_dir typically does not need to be configured.

pub fn register_descriptors(&mut self, descriptors: &[u8]) -> Result<&mut Self>

Register an encoded FileDescriptorSet with this Builder

pub fn register_file_descriptor(
    &mut self,
    file: FileDescriptorProto
) -> &mut Self

Register a decoded FileDescriptor with this Builder

pub fn exclude<S: Into<String>, I: IntoIterator<Item = S>>(
    &mut self,
    prefixes: I
) -> &mut Self

Don’t generate code for the following type prefixes

pub fn retain_enum_prefix(&mut self) -> &mut Self

Configures the code generator to not strip the enum name from variant names.

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

Declare an externally provided Protobuf package or type

pub fn ignore_unknown_fields(&mut self) -> &mut Self

Don’t error out in the presence of unknown fields when deserializing, instead skip the field.

pub fn btree_map<S: Into<String>, I: IntoIterator<Item = S>>(
    &mut self,
    paths: I
) -> &mut Self

Generate Rust BTreeMap implementations for Protobuf map type fields.

pub fn emit_fields(&mut self) -> &mut Self

Output fields with their default values.

pub fn use_integers_for_enums(&mut self) -> &mut Self

pub fn preserve_proto_field_names(&mut self) -> &mut Self

Output fields with their original names as defined in their proto schemas, instead of lowerCamelCase

pub fn build<S: AsRef<str>>(&mut self, prefixes: &[S]) -> Result<()>

Generates code for all registered types where prefixes contains a prefix of the fully-qualified path of the type

pub fn generate<S: AsRef<str>, W: Write, F: FnMut(&Package) -> Result<W>>(
    &self,
    prefixes: &[S],
    write_factory: F
) -> Result<Vec<(Package, W)>>

Generates code into instances of write as provided by the write_factory

This function is intended for use when writing output of code generation directly to output files is not desired. For most use cases inside a build.rs file, the build() method should be preferred.

Trait Implementations

impl Debug for Builder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
