Struct elephantry::Tuple

pub struct Tuple<'a> { /* fields omitted */ }

Represent a set of values, a row of results.

Implementations

impl<'a> Tuple<'a>

pub fn get<T>(&self, name: &str) -> T where
    T: FromSql, 

Retreive the value of field name of the tuple.

Panics

Panics if n is greater than or equal to tuple length.

pub fn try_get<T>(&self, name: &str) -> Result<T> where
    T: FromSql, 

Retreive the value of field name of the tuple, or None if n is greater than or equal to the length of the tuple.

pub fn nth<T>(&self, n: usize) -> T where
    T: FromSql, 

Retreive the nth field.

Panics

Panics if n is greater than or equal to the length of the tuple.

pub fn try_nth<T>(&self, n: usize) -> Result<T> where
    T: FromSql, 

Retreive the nth field, or None if n is greater than or equal to the length of the tuple.

pub fn len(&self) -> usize

Number of field.

pub fn is_empty(&self) -> bool

Is the tuple is empty (doesn’t contain field)?

pub fn field_name(&self, n: usize) -> Option<String>

Retreive the name of field at position n, or None if n is greater than or equal to the length of the tuple.
