Struct SDL_IOWhence 

#[repr(transparent)]
pub struct SDL_IOWhence(pub c_int);

Possible whence values for SDL_IOStream seeking.

These map to the same “whence” concept that fseek or lseek use in the standard C runtime.

Availability

This enum is available since SDL 3.2.0.

Known values (sdl3-sys)

Associated constant	Global constant	Description
SET	SDL_IO_SEEK_SET	Seek from the beginning of data
CUR	SDL_IO_SEEK_CUR	Seek relative to current read point
END	SDL_IO_SEEK_END	Seek relative to the end of data

Tuple Fields

0: c_int

Implementations

impl SDL_IOWhence

Trait Implementations

impl Clone for SDL_IOWhence

fn clone(&self) -> SDL_IOWhence

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SDL_IOWhence

Available on crate feature debug-impls only.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SDL_IOWhence

fn default() -> SDL_IOWhence

Returns the “default value” for a type.

impl From<SDL_IOWhence> for c_int

fn from(value: SDL_IOWhence) -> Self

Converts to this type from the input type.

impl GroupMetadata for SDL_IOWhence

Available on crate feature metadata only.

const GROUP_METADATA: &'static Group

Metadata for this group

impl Hash for SDL_IOWhence

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SDL_IOWhence

fn cmp(&self, other: &SDL_IOWhence) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq<SDL_IOWhence> for c_int

fn eq(&self, other: &SDL_IOWhence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<i32> for SDL_IOWhence

fn eq(&self, other: &c_int) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for SDL_IOWhence

fn eq(&self, other: &SDL_IOWhence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

impl PartialOrd for SDL_IOWhence

fn partial_cmp(&self, other: &SDL_IOWhence) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
