pub struct NitfField<V: FromStr + Debug + Default + Display> {
    pub val: V,
    pub length: usize,
    pub name: String,
}

Lowest level object for file parsing

Fields

val: V

Parsed representation of value

length: usize

Number of bytes used to store value in file

name: String

Name of field

Implementations

impl<V> NitfField<V>

where V: FromStr + Debug + Default + Display, <V as FromStr>::Err: Debug,

Provide default field implementations.

pub fn init(length: u8, name: &str) -> Self

pub fn read(&mut self, reader: &mut (impl Read + Seek)) -> NitfResult<()>

Read the specified number of bytes and parse the value of a given field

pub fn write(&self, writer: &mut (impl Write + Seek)) -> NitfResult<usize>

Trait Implementations

impl<V: Clone + FromStr + Debug + Default + Display> Clone for NitfField<V>

fn clone(&self) -> NitfField<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug + FromStr + Debug + Default + Display> Debug for NitfField<V>

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

Formats the value using the given formatter.

impl<V: Default + FromStr + Debug + Default + Display> Default for NitfField<V>

fn default() -> NitfField<V>

Returns the “default value” for a type.

impl<V: FromStr + Debug + Default + Display> Display for NitfField<V>

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

Formats the value using the given formatter.

impl<V: Ord + FromStr + Debug + Default + Display> Ord for NitfField<V>

fn cmp(&self, other: &NitfField<V>) -> 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<V: PartialEq + FromStr + Debug + Default + Display> PartialEq for NitfField<V>

fn eq(&self, other: &NitfField<V>) -> 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<V: PartialOrd + FromStr + Debug + Default + Display> PartialOrd for NitfField<V>

fn partial_cmp(&self, other: &NitfField<V>) -> 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

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