Functions

delete

</>

pub fn delete(
  query: Dict(String, OneOrMany),
  key: String,
) -> Dict(String, OneOrMany)

empty

</>

pub fn empty() -> Dict(String, OneOrMany)

get

</>

pub fn get(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(OneOrMany, String)

get_as_bool

</>

pub fn get_as_bool(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(Bool, String)

Attempt to get one value as a Bool. If the value is a list this fails. If the value cannot be parsed to a Bool this fails.

get_as_float

</>

pub fn get_as_float(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(Float, String)

Attempt to get one value as an Float. If the value is a list this fail.

get_as_int

</>

pub fn get_as_int(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(Int, String)

Attempt to get one value as an Int. If the value is a list this fails. If the value cannot be parsed to an Int this fails.

get_as_list

</>

pub fn get_as_list(
  query: Dict(String, OneOrMany),
  key: String,
) -> List(String)

Get values from the query as a list of strings (regardless if one or many). If key is not present this defaults to an empty list.

get_as_list_of_bool

</>

pub fn get_as_list_of_bool(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(List(Bool), String)

Attempt to get values as a list of Bool.

get_as_list_of_float

</>

pub fn get_as_list_of_float(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(List(Float), String)

Attempt to get values as a list of Float.

get_as_list_of_int

</>

pub fn get_as_list_of_int(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(List(Int), String)

get_as_string

</>

pub fn get_as_string(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(String, String)

Attempt to get one value as a String. If the value is a list this fails.

</>

pub fn insert(
  query: Dict(String, OneOrMany),
  key: String,
  value: OneOrMany,
) -> Dict(String, OneOrMany)

Insert value.

insert_list

</>

pub fn insert_list(
  query: Dict(String, OneOrMany),
  key: String,
  values: List(String),
) -> Dict(String, OneOrMany)

</>

pub fn maybe_get_as_list(
  query: Dict(String, OneOrMany),
  key: String,
) -> Result(List(String), String)

Get values from the query as a list of strings. If key is not present this returns an Error.

merge
