Fields

format: ExpnFormat

🔬 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?

The format with which the macro was invoked.

allow_internal_unstable: 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 the macro is allowed to use #[unstable]/feature-gated features internally without forcing the whole crate to opt-in to them.

allow_internal_unsafe: 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 the macro is allowed to use unsafe internally even if the user crate has #![forbid(unsafe_code)].

span: Option<Span>

🔬 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?

The span of the macro definition itself. The macro may not have a sensible definition span (e.g. something defined completely inside libsyntax) in which case this is None.
