Struct vector::enrichment_tables::mmdb::Mmdb

pub struct Mmdb { /* private fields */ }

A struct that implements vector_lib::enrichment::Table to handle loading enrichment data from a MaxMind database.

Implementations

impl Mmdb

pub fn new(config: MmdbConfig) -> Result<Self>

Creates a new Mmdb struct from the provided config.

Trait Implementations

impl Clone for Mmdb

fn clone(&self) -> Mmdb

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mmdb

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

Formats the value using the given formatter.

impl Table for Mmdb

fn find_table_row<'a>( &self, case: Case, condition: &'a [Condition<'a>], select: Option<&[String]>, index: Option<IndexHandle>, ) -> Result<ObjectMap, String>

Search the enrichment table data with the given condition. All conditions must match (AND).

Errors

Errors if no rows, or more than 1 row is found.

fn find_table_rows<'a>( &self, _: Case, condition: &'a [Condition<'a>], select: Option<&[String]>, _: Option<IndexHandle>, ) -> Result<Vec<ObjectMap>, String>

Search the enrichment table data with the given condition. All conditions must match (AND). Can return multiple matched records

fn add_index(&mut self, _: Case, fields: &[&str]) -> Result<IndexHandle, String>

Hints to the enrichment table what data is going to be searched to allow it to index the data in advance.

Errors

Errors if the fields are not in the table.

fn index_fields(&self) -> Vec<(Case, Vec<String>)>

Returns a list of the field names that are in each index

fn needs_reload(&self) -> bool

Returns true if the underlying data has changed and the table needs reloading.
