Struct ResponseBuilder 

pub struct ResponseBuilder { /* private fields */ }

A response builder with pre-allocated buffer for efficient response creation.

This builder allocates a buffer upfront and allows building the response body incrementally without reallocations.

Example

use armature_core::response_buffer::ResponseBuilder;

let response = ResponseBuilder::new()
    .status(200)
    .header("Content-Type", "application/json")
    .body_json(&data)?
    .build();
