Function generate_from_config_file 

pub async fn generate_from_config_file<P: AsRef<Path>>(
    config_path: P,
) -> Result<()>

Generates ORM code directly from a configuration file path.

This is a convenience function that combines configuration loading and code generation into a single call. It automatically detects the configuration format (TOML or YAML) and creates the appropriate code generator.

Supported Configuration Formats

• TOML: graphql-codegen-rust.toml or any .toml file
• YAML: codegen.yml, codegen.yaml (requires yaml-codegen-config feature)

Parameters

• config_path: Path to the configuration file. Can be any type that converts to Path.

Returns

• Ok(()) on successful code generation
• Err(anyhow::Error) with context about what failed

Errors

This function can fail due to:

• Configuration file not found or unreadable
• Invalid configuration format or content
• Network issues during GraphQL introspection
• Code generation failures

Example

use graphql_codegen_rust::generate_from_config_file;

// Generate from TOML config
generate_from_config_file("graphql-codegen-rust.toml").await?;

// Generate from YAML config (if feature enabled)
generate_from_config_file("codegen.yml").await?;
