Struct AliasGenerator 

pub struct AliasGenerator { /* private fields */ }

A utility struct that can be used to generate unique aliases when optimizing queries

Implementations

impl AliasGenerator

pub fn new() -> Self

Create a new AliasGenerator

pub fn update_min_id(&self, min_id: usize)

Advance the counter to at least min_id, ensuring future aliases won’t collide with already-existing ones.

For example, if the query already contains an alias alias_42, then calling update_min_id(42) will ensure that future aliases generated by this AliasGenerator will start from alias_43.

pub fn next(&self, prefix: &str) -> String

Return a unique alias with the provided prefix

Trait Implementations

impl Debug for AliasGenerator

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

Formats the value using the given formatter.

impl Default for AliasGenerator

fn default() -> Self

Returns the “default value” for a type.
