Struct Input 

pub struct Input {
    pub path: String,
    pub source: String,
    pub url: String,
    pub sha256: String,
    pub licence: Licence,
    pub provenance: Provenance,
}

One file in a sysroot, and everything that has to be true of it.

Fields

path: String

Where it sits, relative to the sysroot root. Relative because an absolute path is a fact about the machine that built it, and two hosts have different ones.

source: String

What it came out of, named so that the same manifest can be produced again. A release name and version rather than a URL, because a URL moves and a release does not.

url: String

Where that release was fetched from, which is the field section 13.5 asks for by name.

The URL of the release rather than of the file, because what anybody checking this does is download the release and look inside it, and because a per file URL would be a claim about somebody else’s directory layout. It is here in spite of a URL moving and a release not, which is the reason Input::source exists and is not replaced by this: the two fields answer what it is and where it was got, and only the first of those is still true in ten years.

sha256: String

The hash of the file, lowercase hex.

licence: Licence

What it may be done with.

provenance: Provenance

Whether it was bundled, generated or fetched.

Trait Implementations

impl Clone for Input

fn clone(&self) -> Input

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Input

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

Formats the value using the given formatter.

impl Eq for Input

impl Ord for Input

fn cmp(&self, other: &Input) -> 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 Input

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Input

fn partial_cmp(&self, other: &Input) -> 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.
