Struct rustdoc_json::Builder

pub struct Builder { /* private fields */ }

Options for building a rustdoc json file.

See crate for an example on how to use it.

Implementations

impl Builder

pub fn toolchain(self, toolchain: impl Into<Option<String>>) -> Self

Set the toolchain. Default: None. Until rustdoc JSON has stabilized, you will want to set this to be "+nightly" or similar.

If the toolchain is set as None, the current active toolchain will be used.

Notes

The currently active toolchain is typically specified by the RUSTUP_TOOLCHAIN environment variable, which the rustup proxy mechanism sets. See https://rust-lang.github.io/rustup/overrides.html for more info on how the active toolchain is determined.

pub fn manifest_path(self, manifest_path: impl AsRef<Path>) -> Self

Set the relative or absolute path to Cargo.toml. Default: Cargo.toml

pub const fn quiet(self, quiet: bool) -> Self

Whether or not to pass --quiet to cargo rustdoc. Default: false

pub fn target(self, target: String) -> Self

Whether or not to pass --target to cargo rustdoc. Default: None

pub const fn no_default_features(self, no_default_features: bool) -> Self

Whether to pass --no-default-features to cargo rustdoc. Default: false

pub const fn all_features(self, all_features: bool) -> Self

Whether to pass --all-features to cargo rustdoc. Default: false

pub fn features<I: IntoIterator<Item = S>, S: AsRef<str>>(
    self,
    features: I
) -> Self

Features to pass to cargo rustdoc via --features. Default to an empty vector

pub fn package(self, package: impl AsRef<str>) -> Self

Package to use for cargo rustdoc via -p. Default: None

pub fn cap_lints(self, cap_lints: Option<impl AsRef<str>>) -> Self

What to pass as --cap-lints to rustdoc JSON build command

pub fn build(self) -> Result<PathBuf, BuildError>

Generate rustdoc JSON for a library crate. Returns the path to the freshly built rustdoc JSON file.

See crate for an example on how to use it.

Errors

E.g. if building the JSON fails or if the manifest path does not exist or is invalid.
