Trait FromEdn 

pub trait FromEdn: Sized {
    // Required method
    fn from_edn(form: &Edn) -> Result<Self, ClientError>;
}

A Rust value that can be read back out of boundary Edn, for typed extraction from query rows and pull results.

Examples

for row in result.rows() {
    let name: String = row.get(0)?;
    let age: i64 = row.get(1)?;
    println!("{name} is {age}");
}

Required Methods

fn from_edn(form: &Edn) -> Result<Self, ClientError>

Reads self from a boundary Edn form.

Errors

Returns ClientError::Decode when the form is not the expected shape.

Dyn Compatibility

This trait is not dyn compatible.

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