Enum DependencySource 

pub enum DependencySource {
    AssemblyRef(AssemblyRefRc),
    ModuleRef(ModuleRefRc),
    File(FileRc),
}

Source of a dependency relationship within .NET metadata.

This enum identifies which metadata table and specific entry generated a dependency relationship. This information is crucial for:

• Debugging: Tracing dependency issues back to metadata source
• Resolution: Understanding dependency semantics and requirements
• Validation: Ensuring dependency relationships are semantically valid
• Analysis: Building comprehensive dependency reports

Metadata Table Integration

Each variant corresponds to a specific .NET metadata table:

• DependencySource::AssemblyRef ↔ AssemblyRef table (0x23)
• DependencySource::ModuleRef ↔ ModuleRef table (0x1A)
• DependencySource::File ↔ File table (0x26)

Variants

AssemblyRef(AssemblyRefRc)

Dependency from an AssemblyRef table entry

This is the most common dependency source, representing a standard reference to an external assembly. Contains the complete AssemblyRef metadata including version, culture, and strong name information.

ModuleRef(ModuleRefRc)

Dependency from a ModuleRef table entry

Represents a reference to an external module, typically in multi-module assemblies or for P/Invoke scenarios. Less common in modern .NET applications.

File(FileRc)

Dependency from a File table entry

Represents a file within a multi-file assembly. These are intra-assembly dependencies rather than cross-assembly dependencies, but are tracked for completeness and assembly integrity verification.

Implementations

impl DependencySource

pub fn display_name(&self) -> &str

Get the display name for this dependency source.

Returns a human-readable identifier for the dependency source, useful for debugging and error reporting.

Returns

A string slice containing the source’s display name

pub fn dependency_type(&self) -> DependencyType

Get the dependency type based on the source metadata.

Analyzes the source metadata to determine the appropriate dependency type classification. This enables proper handling of different dependency relationship semantics.

Returns

The dependency type that best represents this source’s semantics

Trait Implementations

impl Clone for DependencySource

fn clone(&self) -> DependencySource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencySource

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

Formats the value using the given formatter.

impl Display for DependencySource

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

Formats the value using the given formatter.

impl Eq for DependencySource

impl PartialEq for DependencySource

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

Compare dependency sources for equality.

Two dependency sources are considered equal if they refer to the same dependency, based on the identifying metadata:

• AssemblyRef: Same name, version, culture, and public key token
• ModuleRef: Same module name
• File: Same file name

Different source types are never equal.

Examples

use dotscope::metadata::dependencies::DependencySource;
use dotscope::metadata::identity::AssemblyIdentity;

let id = AssemblyIdentity::parse("Test, Version=1.0.0.0").unwrap();
let source1 = DependencySource::AssemblyRef(id.clone());
let source2 = DependencySource::AssemblyRef(id);

// Two AssemblyRef sources to the same assembly are equal
assert_eq!(source1, source2);

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

Inequality operator !=.
