Struct Compiler 

pub struct Compiler { /* private fields */ }

Schema compiler.

Transforms authoring-time schema definitions into runtime-optimized CompiledSchema with pre-generated SQL templates.

Example

use fraiseql_core::compiler::{Compiler, CompilerConfig, DatabaseTarget};

let config = CompilerConfig {
    database_target: DatabaseTarget::PostgreSQL,
    optimize_sql: true,
    ..Default::default()
};

let compiler = Compiler::with_config(config);
let compiled = compiler.compile(r#"{"types": [], "queries": []}"#)?;

Implementations

impl Compiler

pub fn new() -> Self

Create new compiler with default configuration.

pub const fn with_config(config: CompilerConfig) -> Self

Create new compiler with custom configuration.

pub fn compile(&self, schema_json: &str) -> Result<CompiledSchema>

Compile schema from JSON.

Arguments

• schema_json - JSON schema emitted by the authoring-language decorators

Returns

Compiled schema with pre-generated SQL templates

Errors

Returns error if:

• JSON parsing fails
• Schema validation fails
• SQL template generation fails

Example

use fraiseql_core::compiler::Compiler;

let compiler = Compiler::new();
let schema_json = r#"{"types": [], "queries": []}"#;
let compiled = compiler.compile(schema_json)?;

pub const fn config(&self) -> &CompilerConfig

Get compiler configuration.

Trait Implementations

impl Default for Compiler

fn default() -> Self

Returns the “default value” for a type.
