Implementations§

Source§

impl FilterSet

Source

pub fn from_query_params( params: &HashMap<String, String>, allowed_fields: &[String], ) -> Self

Parses filter parameters from a query string map.

Expects keys in the format filter[field_name]. Only includes filters for fields that are in the allowed_fields list.

Source

pub fn add(&mut self, field: String, value: String)

Adds a filter programmatically (e.g., for tenant scoping).

Source

pub fn is_empty(&self) -> bool

Returns true if there are no filters.

Source

pub fn apply_to_sql( &self, sql: &mut String, has_where: bool, param_offset: usize, ) -> usize

Appends WHERE clauses to the given SQL string.

param_offset is the starting $N parameter index. Returns the new parameter offset after appending.
