Remarks

Struct Remarks 

Source
pub struct Remarks(/* private fields */);
Expand description

What a constant does that the dialect being compiled has an opinion about.

A bitmask rather than a list, because a constant may earn several and a Vec per constant on a file full of them is a cost with nothing to show for it. Every one of these is legal in the dialect this compiler defaults to, so none of them is an error here: the caller decides what -pedantic and -Werror make of them.

Implementations§

Source§

impl Remarks

Source

pub const NONE: Remarks

Nothing to say.

Source

pub const BINARY: Remarks

A 0b constant before C23, where it is a GNU extension both compilers accept.

Source

pub const SEPARATORS: Remarks

A digit separator before C23, which neither compiler accepts there.

Source

pub const BIT_INT: Remarks

A wb suffix before C23.

Source

pub const LONG_LONG: Remarks

An ll suffix under -std=c89, where GCC says “use of C99 long long integer constant”.

Source

pub const UNSIGNED: Remarks

A decimal constant with no u suffix that fits no signed type, so it became an unsigned one. GCC says “integer constant is so large that it is unsigned”, and it is worth saying because the constant’s arithmetic is now unsigned and its negation is not negative.

Source

pub const fn has(self, other: Remarks) -> bool

Whether every remark in other is set here.

Source

pub const fn with(self, other: Remarks) -> Remarks

This set with other added.

Source

pub const fn is_none(self) -> bool

Whether there is nothing to say.
