Struct LicenseExpression 

pub struct LicenseExpression {
    pub expression: String,
    pub is_valid_spdx: bool,
    pub resolved_name: Option<String>,
}

License expression following SPDX license expression syntax

Fields

expression: String

The raw license expression string

is_valid_spdx: bool

Whether this is a valid SPDX expression

resolved_name: Option<String>

Human-readable name resolved from the document’s license definitions (e.g. SPDX hasExtractedLicensingInfos for a bare LicenseRef-* expression). Display metadata only: excluded from equality/hashing below so identical expressions stay equal (and pre-existing serialized SBOMs stay diff-identical) whether or not resolution ran.

Implementations

impl LicenseExpression

pub fn new(expression: String) -> Self

Create a new license expression

pub fn display_name(&self) -> &str

Human-readable display form: the name resolved from the document’s license definitions (e.g. SPDX hasExtractedLicensingInfos for a bare LicenseRef-*) when present, otherwise the raw expression. For rendering/emit only — equality and identity stay on expression.

pub fn from_spdx_id(id: &str) -> Self

Create from an SPDX license ID

pub fn is_permissive(&self) -> bool

Check if this expression includes a permissive license option.

For OR expressions (e.g., “MIT OR GPL-2.0”), returns true if at least one branch is permissive (the licensee can choose the permissive option). Falls back to substring matching for non-parseable expressions.

pub fn is_copyleft(&self) -> bool

Check if this expression requires copyleft compliance.

Returns true if any license term in the expression is copyleft. Falls back to substring matching for non-parseable expressions.

pub fn family(&self) -> LicenseFamily

Get the license family classification.

For compound expressions:

• OR: returns the most permissive option (licensee can choose)
• AND: returns the most restrictive requirement Falls back to substring matching for non-parseable expressions.

Trait Implementations

impl Clone for LicenseExpression

fn clone(&self) -> LicenseExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LicenseExpression

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

Formats the value using the given formatter.

impl Default for LicenseExpression

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LicenseExpression

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LicenseExpression

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

Formats the value using the given formatter.

impl Eq for LicenseExpression

impl Hash for LicenseExpression

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 PartialEq for LicenseExpression

Equality/hashing deliberately ignore resolved_name: the raw expression is the license identity.

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for LicenseExpression

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
