Trait TryGetable 

pub trait TryGetable: Sized {
    // Required method
    fn try_get_by<I: ColIdx>(
        res: &QueryResult,
        index: I,
    ) -> Result<Self, TryGetError>;

    // Provided methods
    fn try_get(
        res: &QueryResult,
        pre: &str,
        col: &str,
    ) -> Result<Self, TryGetError> { ... }
    fn try_get_by_index(
        res: &QueryResult,
        index: usize,
    ) -> Result<Self, TryGetError> { ... }
}

Decode a single column value out of a QueryResult.

Implemented for every primitive SeaORM understands (integers, strings, booleans, JSON, UUIDs, chrono / time types when their features are enabled, etc.). User code rarely names this trait directly; it’s the foundation that FromQueryResult builds on.

Required Methods

fn try_get_by<I: ColIdx>( res: &QueryResult, index: I, ) -> Result<Self, TryGetError>

Decode the value at the column named or positioned by index.

Provided Methods

fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, TryGetError>

Decode the value at column {pre}{col} — pre is the prefix used when nesting partial models or joining tables.

fn try_get_by_index( res: &QueryResult, index: usize, ) -> Result<Self, TryGetError>

Decode the value at the given positional index in the SELECT list.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
