Enum guppy::graph::PackageSource

pub enum PackageSource<'g> {
    Workspace(&'g Utf8Path),
    Path(&'g Utf8Path),
    External(&'g str),
}

The source of a package.

This enum contains information about where a package is found, and whether it is inside or outside the workspace.

Variants

Workspace(&'g Utf8Path)

This package is in the workspace.

The path is relative to the workspace root.

Path(&'g Utf8Path)

This package is a path dependency that isn’t in the workspace.

The path is relative to the workspace root.

External(&'g str)

This package is an external dependency.

• For packages retrieved from crates.io, the source is the string "registry+https://github.com/rust-lang/crates.io-index".
• For packages retrieved from other registries, the source begins with "registry+".
• For packages retrieved from Git repositories, the source begins with "git+".

Implementations

impl<'g> PackageSource<'g>

pub const CRATES_IO_REGISTRY: &'static str = "registry+https://github.com/rust-lang/crates.io-index"

The path to the crates.io registry.

pub fn is_workspace(&self) -> bool

Returns true if this package source represents a workspace.

pub fn is_path(&self) -> bool

Returns true if this package source represents a path dependency that isn’t in the workspace.

pub fn is_external(&self) -> bool

Returns true if this package source represents an external dependency.

pub fn is_crates_io(&self) -> bool

Returns true if the source is crates.io.

pub fn is_local(&self) -> bool

Returns true if this package is a local dependency, i.e. either in the workspace or a local path.

pub fn workspace_path(&self) -> Option<&'g Utf8Path>

Returns the path if this is a workspace dependency, or None if this is a non-workspace dependency.

The path is relative to the workspace root.

pub fn local_path(&self) -> Option<&'g Utf8Path>

Returns the local path if this is a local dependency, or None if it is an external dependency.

The path is relative to the workspace root.

pub fn external_source(&self) -> Option<&'g str>

Returns the external source if this is an external dependency, or None if it is a local dependency.

pub fn parse_external(&self) -> Option<ExternalSource<'g>>

Attempts to parse an external source.

Returns None if the external dependency could not be recognized, or if it is a local dependency.

For more about external sources, see the documentation for ExternalSource.

Trait Implementations

impl<'g> Clone for PackageSource<'g>

fn clone(&self) -> PackageSource<'g>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'g> Debug for PackageSource<'g>

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

Formats the value using the given formatter.

impl<'g> Display for PackageSource<'g>

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

Formats the value using the given formatter.

impl<'g> Hash for PackageSource<'g>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'g> PartialEq for PackageSource<'g>

fn eq(&self, other: &PackageSource<'g>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
