Struct llvm_plugin_inkwell::attributes::Attribute

source · [−]

pub struct Attribute { /* private fields */ }

Expand description

Functions, function parameters, and return types can have Attributes to indicate how they should be treated by optimizations and code generation.

Implementations

source

impl Attribute

source

pub fn is_enum(self) -> bool

Determines whether or not an Attribute is an enum. This method will likely be removed in the future in favor of Attributes being generically defined.

Example

use inkwell::context::Context;

let context = Context::create();
let enum_attribute = context.create_enum_attribute(0, 10);

assert!(enum_attribute.is_enum());

source

pub fn is_string(self) -> bool

Determines whether or not an Attribute is a string. This method will likely be removed in the future in favor of Attributes being generically defined.

Example

use inkwell::context::Context;

let context = Context::create();
let string_attribute = context.create_string_attribute("my_key_123", "my_val");

assert!(string_attribute.is_string());

source

pub fn get_named_enum_kind_id(name: &str) -> u32

Gets the enum kind id associated with a builtin name.

Example

use inkwell::attributes::Attribute;

// This kind id doesn't exist:
assert_eq!(Attribute::get_named_enum_kind_id("foobar"), 0);

// These are real kind ids:
assert_eq!(Attribute::get_named_enum_kind_id("align"), 1);
assert_eq!(Attribute::get_named_enum_kind_id("builtin"), 5);

source

pub fn get_enum_kind_id(self) -> u32

Gets the kind id associated with an enum Attribute.

Example

use inkwell::context::Context;

let context = Context::create();
let enum_attribute = context.create_enum_attribute(0, 10);

assert_eq!(enum_attribute.get_enum_kind_id(), 0);

source

pub fn get_last_enum_kind_id() -> u32

Gets the last enum kind id associated with builtin names.

Example

use inkwell::attributes::Attribute;

assert_eq!(Attribute::get_last_enum_kind_id(), 56);

source

pub fn get_enum_value(self) -> u64

Gets the value associated with an enum Attribute.

Example

use inkwell::context::Context;

let context = Context::create();
let enum_attribute = context.create_enum_attribute(0, 10);

assert_eq!(enum_attribute.get_enum_value(), 10);

source

pub fn get_string_kind_id(&self) -> &CStr

Gets the string kind id associated with a string attribute.

Example

use inkwell::context::Context;

let context = Context::create();
let string_attribute = context.create_string_attribute("my_key", "my_val");

assert_eq!(string_attribute.get_string_kind_id().to_str(), Ok("my_key"));

source

pub fn get_string_value(&self) -> &CStr

Gets the string value associated with a string attribute.

Example

use inkwell::context::Context;

let context = Context::create();
let string_attribute = context.create_string_attribute("my_key", "my_val");

assert_eq!(string_attribute.get_string_value().to_str(), Ok("my_val"));
