Enum SaveTemps 

pub enum SaveTemps {
    No,
    Object,
    Cwd,
}

Whether -save-temps was given and where it puts the files it keeps.

Design: spec/04-driver-and-cli.md section 4.10.

The flag is how a build gets at the preprocessed source of the file that failed without running the compiler a second time under different flags, which is the one way to be sure the text being read is the text that was compiled. A bug report against a compiler is usually a preprocessed file and nothing else, and this is where that file comes from.

Variants

No

Not asked for, and nothing is kept.

Object

Beside the file the compilation produced, which is -save-temps=obj.

This is what the bare -save-temps does as well. GCC’s manual says the bare spelling is -save-temps=cwd, and gcc 16 does not do that: -save-temps -c a.c -o out/a.o leaves out/a.i and out/a.s rather than a.i and a.s. The measurement is what is followed here, because a build that reads the manual and a build that reads the compiler both end up looking for the files where the compiler put them.

Cwd

In the working directory, which is -save-temps=cwd.

Implementations

impl SaveTemps

pub const fn wanted(self) -> bool

Whether anything is kept at all.

Trait Implementations

impl Clone for SaveTemps

fn clone(&self) -> SaveTemps

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SaveTemps

impl Debug for SaveTemps

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

Formats the value using the given formatter.

impl Default for SaveTemps

fn default() -> SaveTemps

Returns the “default value” for a type.

impl Eq for SaveTemps

impl FromStr for SaveTemps

fn from_str(s: &str) -> Result<SaveTemps, String>

Reads what came after the =, which is the only part that varies.

Errors

Returns the offending word. GCC treats an unknown one as fatal rather than ignoring it, which is right: a misspelled keyword here means the files a person went looking for are not written and nothing said so.

type Err = String

The associated error which can be returned from parsing.

impl PartialEq for SaveTemps

fn eq(&self, other: &SaveTemps) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
