Struct btfproto::msg::Flags

pub struct Flags(_);

A wrapper type around i32 with convenience methods for checking if libc::O_* flags have been set.

Implementations

impl Flags

pub const fn new(value: i32) -> Self

Wraps the given i32 value.

pub const fn value(self) -> i32

Returns the inner i32 value.

pub const fn writeable(self) -> bool

Returns true if these flags allow the file to be written to.

pub const fn readable(self) -> bool

Returns true if these flags allow the file to be read from.

pub const fn read_only(self) -> bool

Returns true if the file was opened readonly.

pub const fn write_only(self) -> bool

Returns true if the file was opened writeonly

pub const fn directory(self) -> bool

Returns true if these flags are for a directory.

pub const fn process(self) -> bool

Returns true if these flags are for a process.

pub const fn server(self) -> bool

Returns true if these flags are for a server.

pub fn assert_readable(self) -> Result<(), Error>

Asserts that these flags allow a file to be read.

If the assertion fails then an io::Error with the errno [libc::EACCES] is returned.

pub fn assert_writeable(self) -> Result<(), Error>

Asserts that these flags allow a file to be written.

If the assertion fails then an io::Error with the errno [libc::EACCES] is returned.

Trait Implementations

impl BitOr<FlagValue> for Flags

type Output = Flags

The resulting type after applying the | operator.

fn bitor(self, rhs: FlagValue) -> Self::Output

Performs the | operation.

impl BitOr<Flags> for Flags

type Output = Flags

The resulting type after applying the | operator.

fn bitor(self, rhs: Flags) -> Self::Output

Performs the | operation.

impl Clone for Flags

fn clone(&self) -> Flags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Flags

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

Formats the value using the given formatter.

impl Default for Flags

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Flags

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Flags

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

Formats the value using the given formatter.

impl From<FlagValue> for Flags

fn from(flag_value: FlagValue) -> Self

Converts to this type from the input type.

impl From<Flags> for i32

fn from(flags: Flags) -> Self

Converts to this type from the input type.

impl From<i32> for Flags

fn from(value: i32) -> Self

Converts to this type from the input type.

impl Hash for Flags

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 PartialEq<Flags> for Flags

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Flags

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
