Struct querystrong::QueryStrong

pub struct QueryStrong(_);

Implementations

impl QueryStrong

pub fn new() -> Self

Creates a new (empty) querystrong that contains a map as the top level value

pub fn parse(s: &str) -> Result<Self>

Attempts to create a build a querystrong from the supplied querystring

Methods from Deref<Target = Value>

pub fn is_map(&self) -> bool

pub fn is_string(&self) -> bool

pub fn is_list(&self) -> bool

pub fn as_slice(&self) -> Option<&[Self]>

pub fn as_map(&self) -> Option<&BTreeMap<String, Value>>

pub fn as_str(&self) -> Option<&str>

pub fn is_empty(&self) -> bool

this is a general-purpose predicate that is broader than just whether the value is an Empty. Zero-length Values of any sort will return true from is_empty

pub fn len(&self) -> usize

pub fn append(
    &mut self,
    key: impl Into<IndexPath>,
    value: impl Into<Value>
) -> Result<()>

pub fn get(&self, key: impl Into<IndexPath>) -> Option<&Value>

pub fn get_str(&self, key: impl Into<IndexPath>) -> Option<&str>

pub fn get_slice(&self, key: impl Into<IndexPath>) -> Option<&[Value]>

pub fn get_map(
    &self,
    key: impl Into<IndexPath>
) -> Option<&BTreeMap<String, Value>>
