Struct Args 

pub struct Args {
    pub flavor: Flavor,
    /* private fields */
}

Args store SQL-related arguments and index mappings.

Fields

flavor: Flavor

Default flavor used by compile.

Implementations

impl Args

pub fn add(&mut self, arg: impl Into<Arg>) -> String

Add: push an argument and return the internal placeholder ($0/$1/...).

pub fn replace(&mut self, placeholder: &str, arg: impl Into<Arg>)

Replace: swap the value bound to a $n placeholder.

pub fn value(&self, placeholder: &str) -> Option<&Arg>

Value: parse a placeholder with $<n> prefix (lenient match).

• placeholder may have suffix (e.g. "$0xxx"); as long as it starts with $<digits> it will be parsed.

pub fn compile(&self, format: &str, initial_value: &[Arg]) -> (String, Vec<Arg>)

Compile: build SQL using the default flavor.

pub fn compile_with_flavor( &self, format: &str, flavor: Flavor, initial_value: &[Arg], ) -> (String, Vec<Arg>)

CompileWithFlavor: build SQL using a specific flavor.
