pub struct TemplateArg<'q, DB: Database> { /* private fields */ }

SQL template argument processor

Handles parameter encoding and binding for SQL templates

Implementations

impl<'q, DB: Database> TemplateArg<'q, DB>

pub fn encode<T>(&self, t: T) -> String

where T: Encode<'q, DB> + Type<DB> + 'q,

Encodes a single parameter and returns its placeholder

Arguments

• t - Value to encode

Returns

Parameter placeholder string (e.g. “$1” or “?”)

pub fn encode_list<T>(&self, args: impl Iterator<Item = T>) -> String

where T: Encode<'q, DB> + Type<DB> + 'q,

Encodes a parameter list and returns placeholder sequence

Arguments

• args - Iterator of values to encode

Returns

Parameter placeholder sequence (e.g. “($1,$2,$3)”)

pub fn get_err(&self) -> Option<BoxDynError>

Takes any encoding error that occurred

pub fn get_arguments(&self) -> Option<DB::Arguments<'q>>

Takes ownership of the encoded arguments
