Implementations

impl SqlRow

pub fn get(&self, name: &str) -> Option<&SqlValue>

Look up a column value by name, returning None if absent.

pub fn text(&self, name: &str) -> Result<&str, SqlColumnError>

Read text, refusing NULL, absence, and other SQL variants.

pub fn i64(&self, name: &str) -> Result<i64, SqlColumnError>

Read an integer, refusing NULL, absence, and other SQL variants, including Float.

pub fn opt_text(&self, name: &str) -> Result<Option<&str>, SqlColumnError>

Read nullable text, refusing an absent column or another SQL variant.

pub fn opt_i64(&self, name: &str) -> Result<Option<i64>, SqlColumnError>

Read a nullable integer, refusing an absent column or another SQL variant.

pub fn opt_text_or_absent( &self, name: &str, ) -> Result<Option<&str>, SqlColumnError>

Read nullable text, treating absence as NULL while refusing other SQL variants.

pub fn opt_i64_or_absent( &self, name: &str, ) -> Result<Option<i64>, SqlColumnError>

Read a nullable integer, treating absence as NULL while refusing other SQL variants.

pub fn uuid(&self, name: &str) -> Result<Uuid, SqlColumnError>

Read a native UUID or parse UUID text, refusing NULL, absence, invalid UUID text, and other SQL variants.

pub fn opt_uuid(&self, name: &str) -> Result<Option<Uuid>, SqlColumnError>

Read a nullable UUID with the same accepted representations as Self::uuid. An absent column, invalid UUID text, or another SQL variant is refused.

pub fn f64(&self, name: &str) -> Result<f64, SqlColumnError>

Read a Float unchanged or convert an Integer using Rust’s as f64 rounding. Non-finite Floats are preserved; NULL, absence, and other SQL variants (including numeric text) are refused.

pub fn opt_f64(&self, name: &str) -> Result<Option<f64>, SqlColumnError>

Read a nullable number using Self::f64, refusing an absent column or another SQL variant.

pub fn text_or_none(&self, name: &str) -> Option<&str>

Read text, treating absence, NULL, and every other SQL variant as None.

pub fn i64_or_none(&self, name: &str) -> Option<i64>

Read an integer, treating absence, NULL, and every other SQL variant (including Float) as None.
