\ingroup filters

Fields

_canary: i32

terms: [ecs_term_t; 16]

Terms of the filter. If a filter has more terms than FLECS_TERM_DESC_MAX use terms_buffer

terms_buffer: *mut ecs_term_t

For filters with lots of terms an outside array can be provided.

terms_buffer_count: i32

Number of terms in array provided in terms_buffer.

storage: *mut ecs_filter_t

External storage to prevent allocation of the filter object

instanced: bool

When true, terms returned by an iterator may either contain 1 or N elements, where terms with N elements are owned, and terms with 1 element are shared, for example from a parent or base entity. When false, the iterator will at most return 1 element when the result contains both owned and shared terms.

flags: u32

Flags for advanced usage

expr: *const i8

Filter expression. Should not be set at the same time as terms array

entity: u64

Entity associated with query (optional)
