Enum AttributeFilter 

pub enum AttributeFilter {
    KeepAll,
    Exclude(HashSet<String>),
    Include(HashSet<String>),
    ExcludeAll,
}

Opt-in user-property selection (tippecanoe --exclude/--include/ --exclude-all mental model). Applied at the point property columns are materialised, so it governs BOTH point/line/polygon layers and clipped trajectory-segment layers.

SYSTEM columns (feature id, start/end time, geometry, vertex_time / vertex_value / vertex_value_matrix, triangles) are NOT user properties and are therefore never reachable here — they always survive. This filter only ever touches the properties map.

Variants

KeepAll

No filtering — every user property is kept (the default; byte-for-byte identical to a build with none of the attribute flags set).

Exclude(HashSet<String>)

Drop exactly these property names (--exclude).

Include(HashSet<String>)

Keep ONLY these property names (--include).

ExcludeAll

Drop every user property — geometry + times only (--exclude-all).

Implementations

impl AttributeFilter

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

Should the named user property be emitted?

pub fn is_keep_all(&self) -> bool

True when the filter is the inert default (no property is ever dropped).

Trait Implementations

impl Clone for AttributeFilter

fn clone(&self) -> AttributeFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeFilter

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

Formats the value using the given formatter.

impl Default for AttributeFilter

fn default() -> AttributeFilter

Returns the “default value” for a type.
