Enum DetectedVersion 

pub enum DetectedVersion {
    Declared(VastVersion),
    Inferred(VastVersion),
    DeclaredAndInferred {
        declared: VastVersion,
        inferred: VastVersion,
        consistent: bool,
    },
    Unknown,
}

How the version was determined.

Version detection is a two-pass process: first the version attribute on the root <VAST> element is read (declared), then the document structure is scanned for version-specific elements (inferred). When both are available, consistency is checked and a mismatch produces a warning.

Variants

Declared(VastVersion)

Version attribute was present and recognised.

Inferred(VastVersion)

Version attribute was absent or unrecognised; version inferred from document structure.

DeclaredAndInferred

Both declared and inferred — may or may not agree.

Fields

declared: VastVersion

inferred: VastVersion

consistent: bool

Unknown

Could not determine version.

Implementations

impl DetectedVersion

pub fn best(&self) -> Option<&VastVersion>

Returns the best available version, preferring the declared value.

Trait Implementations

impl Clone for DetectedVersion

fn clone(&self) -> DetectedVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DetectedVersion

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

Formats the value using the given formatter.

impl PartialEq for DetectedVersion

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