Struct stam::QueryNames

source ·

pub struct QueryNames(/* private fields */);

Expand description

This is a simple hashmap that can resolve all variable names used in the query to the internally used index numbers See AnnotationStore::query() for an example.

Implementations§

source §

impl QueryNames

source

pub fn get(&self, name: &str) -> Result<usize, StamError>

Get the index for a given variable name, do not include the ? prefix STAMQL uses.

source

pub fn enumerate(&self) -> Vec<(usize, &str)>

Iterate over all the variable names and returns them in order. The ? prefix STAMQL uses will never be included.
