Trait PrecomputeSize 

pub trait PrecomputeSize {
    // Required method
    fn pre_compute_size(&self, options: &Options, sizes: &mut Vec<Size>) -> Size;
}

Computation of the printed layout, ahead of printing.

Implementations push one Size per array/object encountered, in depth-first order, and return the size of the value itself.

Recurses once per nesting level; each level runs through on_sufficient_stack.

Required Methods

fn pre_compute_size(&self, options: &Options, sizes: &mut Vec<Size>) -> Size

Computes the printed size of this value, appending the size of each nested array and object to sizes.

Dyn Compatibility

This trait is dyn compatible.

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