Struct PlaceholderGen 

pub struct PlaceholderGen { /* private fields */ }

Hands out positional bind placeholders in sequence (?1/$1, ?2/$2, …) for the given dialect, so a query builder doesn’t track indices by hand.

Implementations

impl PlaceholderGen

pub fn new(dialect: SqlDialect) -> Self

Start a generator for dialect; the first placeholder is number 1.

pub fn next_placeholder(&mut self) -> String

Render the next placeholder and advance the counter.
