Struct PartNumber 

pub struct PartNumber(/* private fields */);

Number we assign to a part when uploading.

This, along with the entity tag found in the response, is required in the request to complete a multipart upload because it identifies the where the part goes when assembling the full object.

The Default behavior is to start with the part number 1. This is because it is a requirement of the API that a part number be an integer between 1 and 10,000.

Implementations

impl PartNumber

pub fn new() -> Self

Initializes the part number at 1, which is a requirement of the API.

pub fn start_with(n: i32) -> Self

Create a new PartNumber starting with n.

Used when resuming an upload that was suspended with completed parts.

For a new upload, use Self::new.

pub fn is_first(&self) -> bool

Returns whether this is the first part of an upload.

pub fn is_valid(&self) -> bool

Returns whether this is a valid part according to API specification.

pub fn fetch_incr(&mut self) -> PartNumber

Increment the PartNumber by 1, returning the previous part number.

Methods from Deref<Target = i32>

pub const MIN: i32

pub const MAX: i32

pub const BITS: u32 = u32::BITS

Trait Implementations

impl Clone for PartNumber

fn clone(&self) -> PartNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartNumber

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

Formats the value using the given formatter.

impl Default for PartNumber

fn default() -> Self

Returns the “default value” for a type.

impl Deref for PartNumber

type Target = i32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for PartNumber

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Display for PartNumber

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

Formats the value using the given formatter.

impl Hash for PartNumber

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 PartNumber

fn cmp(&self, other: &PartNumber) -> 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 for PartNumber

fn eq(&self, other: &PartNumber) -> 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 PartialOrd for PartNumber

fn partial_cmp(&self, other: &PartNumber) -> 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.
