API Reference

Symbol-level documentation for Quark's public API: signatures, parameters, and exact behaviour, grouped the same way the sidebar is.

Use these pages when you know what you want to call and need the details. If you are still working out how to do something, the Guides cover the same ground as walkthroughs.

Quick Example

package main

import (
    "context"

    "github.com/jcsvwinston/quark"
    _ "github.com/jcsvwinston/quark/drivers/postgres"
)

type User struct {
    ID    int64  `db:"id" pk:"true"`
    Name  string `db:"name"`
    Email string `db:"email" quark:"unique"`
}

func main() {
    client, _ := quark.New("pgx", "...")
    ctx := context.Background()
    
    // Create
    user := &User{Name: "Alice", Email: "alice@example.com"}
    quark.For[User](ctx, client).Create(user)
    // => user.ID is populated with the generated primary key

    // Read
    u, _ := quark.For[User](ctx, client).Find(user.ID)
    // => u is the matching User; err is quark.ErrNotFound if no row exists

    // Query
    users, _ := quark.For[User](ctx, client).
        Where("active", "=", true).
        OrderBy("created_at", "DESC").
        List()
    // => users is a []User of active rows, newest first

    // Update
    u.Name = "Alice Smith"
    quark.For[User](ctx, client).Update(&u)
    // => returns (rowsAffected int64, err error)

    // Delete
    quark.For[User](ctx, client).Delete(&u)
    // => returns (rowsAffected int64, err error)
}
