Struct DependencySpec 

pub struct DependencySpec {
    pub name: String,
    pub version_req: String,
}

Parsed dependency specification (name with optional version requirement).

Result of parsing a dependency string like “python>=3.12” or “glibc”.

Fields

name: String

Package name.

version_req: String

Version constraint (may be empty if no constraint specified).

Implementations

impl DependencySpec

pub fn new(name: impl Into<String>) -> Self

What: Create a new dependency spec with just a name.

Inputs:

• name: Package name (will be converted to String).

Output:

• Returns a new DependencySpec with empty version requirement.

Details:

• Convenience constructor for dependencies without version constraints.

pub fn with_version( name: impl Into<String>, version_req: impl Into<String>, ) -> Self

What: Create a new dependency spec with name and version requirement.

Inputs:

• name: Package name (will be converted to String).
• version_req: Version requirement string (e.g., “>=1.2.3”).

Output:

• Returns a new DependencySpec with both name and version requirement.

Details:

• Convenience constructor for dependencies with version constraints.

pub const fn has_version_req(&self) -> bool

What: Check if this spec has a version requirement.

Inputs:

• self: The dependency spec to check.

Output:

• Returns true if a version requirement is specified.

Details:

• Checks if version_req is non-empty.

Trait Implementations

impl Clone for DependencySpec

fn clone(&self) -> DependencySpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencySpec

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

Formats the value using the given formatter.

impl Default for DependencySpec

fn default() -> DependencySpec

Returns the “default value” for a type.

impl Display for DependencySpec

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

Formats the value using the given formatter.

impl PartialEq for DependencySpec

fn eq(&self, other: &DependencySpec) -> 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.
