Trait FromValue 

pub trait FromValue: Sized {
    // Required method
    fn from_value(val: Value) -> Result<Self>;
}

Converts a libsql::Value into a concrete Rust type.

This trait mirrors the sealed FromValue inside libsql, providing the same conversions for use with ColumnMap::get.

Implemented for: String, i32, i64, u32, u64, f64, bool, Vec<u8>, Option<T> (where T: FromValue), and libsql::Value.

Required Methods

fn from_value(val: Value) -> Result<Self>

Convert a value into Self.

Errors

Returns an error on type mismatch or unexpected null.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
