Struct DependencyCollector 

pub struct DependencyCollector { /* private fields */ }

Tracks package dependencies with versions and features.

Example

use baobao_codegen::{DependencyCollector, DependencySpec};

let mut deps = DependencyCollector::new();
deps.add("serde", DependencySpec::new("1.0").with_features(["derive"]));
deps.add("tokio", DependencySpec::new("1").with_features(["rt-multi-thread", "macros"]));

for (name, spec) in deps.iter() {
    println!("{} = \"{}\"", name, spec.version);
}

Implementations

impl DependencyCollector

pub fn new() -> Self

Create a new empty dependency collector.

pub fn add(&mut self, name: impl Into<String>, spec: DependencySpec)

Add a dependency. If it already exists, this is a no-op.

pub fn add_simple( &mut self, name: impl Into<String>, version: impl Into<String>, )

Add a simple dependency with just a version.

pub fn has(&self, name: &str) -> bool

Check if a dependency exists.

pub fn get(&self, name: &str) -> Option<&DependencySpec>

Get a dependency spec.

pub fn iter(&self) -> impl Iterator<Item = (&str, &DependencySpec)>

Iterate over all dependencies.

pub fn sorted(&self) -> Vec<(&str, &DependencySpec)>

Get dependencies sorted by name for deterministic output.

pub fn is_empty(&self) -> bool

Check if the collector is empty.

pub fn len(&self) -> usize

Get the number of dependencies.

Trait Implementations

impl Clone for DependencyCollector

fn clone(&self) -> DependencyCollector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencyCollector

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

Formats the value using the given formatter.

impl Default for DependencyCollector

fn default() -> DependencyCollector

Returns the “default value” for a type.
