Enum Licence 

pub enum Licence {
    Mit,
    Lgpl,
    Bsd,
    MingwPermissive,
    Apache2,
    AppleSdk,
    MicrosoftSdk,
}

The licence an input arrives under.

The list is section 8.2’s table with one variant per row, rather than a free text field, because the question Licence::redistributable answers has to have an answer for every input and a string does not.

Variants

Mit

musl, which is MIT and the reason it goes first.

Lgpl

glibc, which is LGPL. Redistributable, with obligations that spec/cross-compile/13-distribution.md owns.

Bsd

The BSD libcs, which are permissive.

MingwPermissive

mingw-w64, which is a mix of permissive licences and public domain headers.

Apache2

Ours. The compiler’s own headers and its runtime.

AppleSdk

The macOS SDK, restricted by the Xcode agreement to Apple-branded hardware. Never shipped, only ever pointed at.

MicrosoftSdk

The Windows SDK and the universal CRT, which are not redistributable.

Implementations

impl Licence

pub const fn redistributable(self) -> bool

Whether an artifact containing this input can be published.

Two of the seven answer false, and they are the two section 8.6 calls legal walls rather than engineering. A sysroot containing either is a local thing on the machine of somebody who accepted the licence themselves.

pub const fn as_str(self) -> &'static str

The spelling in a manifest file.

Trait Implementations

impl Clone for Licence

fn clone(&self) -> Licence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Licence

impl Debug for Licence

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

Formats the value using the given formatter.

impl Display for Licence

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

Formats the value using the given formatter.

impl Eq for Licence

impl FromStr for Licence

type Err = ManifestError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Licence

fn cmp(&self, other: &Licence) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Licence

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Licence

fn partial_cmp(&self, other: &Licence) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
