Specification of a single lint.

Fields

name: &'static str

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A string identifier for the lint.

This identifies the lint in attributes and in command-line arguments. In those contexts it is always lowercase, but this field is compared in a way which is case-insensitive for ASCII characters. This allows declare_lint!() invocations to follow the convention of upper-case statics without repeating the name.

The name is written with underscores, e.g. "unused_imports". On the command line, underscores become dashes.

default_level: Level

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Default level for the lint.

desc: &'static str

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Description of the lint or the issue it detects.

e.g. "imports that are never used"

edition_lint_opts: Option<(Edition, Level)>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Starting at the given edition, default to the given lint level. If this is None, then use default_level.

report_in_external_macro: bool

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Whether this lint is reported even inside expansions of external macros
