Struct DependencyResolver 

pub struct DependencyResolver { /* private fields */ }

Resolves startup order from the dependency graph declared in a DevrigConfig.

The graph is unified: it contains service nodes, docker nodes, and compose service nodes. Edges point from dependency to dependent (i.e. if service B depends on docker A, the edge is A -> B). A topological sort yields the correct startup order: dependencies before their dependents.

Implementations

impl DependencyResolver

pub fn from_config(config: &DevrigConfig) -> Result<Self, String>

Build a unified dependency graph from a DevrigConfig.

Includes services, docker, and compose service nodes. Returns an error if any node lists a dependency that is not defined anywhere.

pub fn start_order(&self) -> Result<Vec<(String, ResourceKind)>, String>

Return a valid startup order (dependencies first) with resource kind info.

Returns an error if the graph contains a cycle.

pub fn start_order_names(&self) -> Result<Vec<String>, String>

Return just the names in startup order (for backward compatibility).

pub fn resource_kind(&self, name: &str) -> Option<ResourceKind>

Look up the resource kind for a given name.

Trait Implementations

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

Formats the value using the given formatter.
