[−][src]Struct jsonp::BackingBytes
Convenience wrapper around the library core functions for byte slices, removing some of the generic noise from function signatures.
Implementations
impl<'a> BackingBytes<'a>
[src]
pub fn new(borrow: &'a [u8]) -> Self
[src]
Instantiate a wrapper around the given byte slice.
pub fn with(borrow: &'a [u8], pointer: Pointer) -> Self
[src]
Instantiate a wrapper around the given byte slice and pointer.
pub fn dotted<'de, T>(&self, pointer: &str) -> Result<T, Error> where
T: Deserialize<'de>,
'a: 'de,
[src]
T: Deserialize<'de>,
'a: 'de,
See the documentation of Pointer::dotted
.
Example
use jsonp::BackingBytes; fn main() { let json = r#"{"outer": {"array": [0, "one", true]}}"#.as_bytes(); let one: &str = BackingBytes::new(json).dotted("outer.array.1").unwrap(); assert!(one == "one"); }
pub fn pattern<'de, T>(&self, pointer: &str, pattern: &str) -> Result<T, Error> where
T: Deserialize<'de>,
'a: 'de,
[src]
T: Deserialize<'de>,
'a: 'de,
See the documentation of Pointer::with_pattern
.
Example
use jsonp::BackingBytes; fn main() { let json = r#"{"outer": {"array": [0, "one", true]}}"#.as_bytes(); let is_true: bool = BackingBytes::new(json).pattern("outer array 2", " ").unwrap(); assert!(is_true); }
pub fn pointer<'de, 'p, I, T>(&self, pointers: I) -> Result<T, Error> where
I: IntoIterator<Item = Segment<'p>>,
T: Deserialize<'de>,
'a: 'de,
[src]
I: IntoIterator<Item = Segment<'p>>,
T: Deserialize<'de>,
'a: 'de,
See the documentation for Pointer::with_segments
.
Example
use jsonp::{BackingBytes, Segment}; fn main() { let json = r#"{"outer": {"array": [0, 1, 2, 3]}}"#.as_bytes(); let segments = &["outer", "array"]; let array: Vec<i8> = BackingBytes::new(json) .pointer(segments.into_iter().copied().map(Segment::lazy)) .unwrap(); assert_eq!(&array, &[0, 1, 2, 3]); }
