Data::Sah::Util::Role - Sah utility routines for roles
version 0.21
This module provides some utility routines to be used in roles, e.g. Data::Sah::Type::* and Data::Sah::FuncSet::*.
Data::Sah::Type::*
Data::Sah::FuncSet::*
Define a clause. Used in type roles (Data::Sah::Type::*). Internally it adds a Moo requires for clause_$name.
requires
clause_$name
Options:
arg => $schema
Define schema for clause value.
prio => $priority
Optional. Default is 50. The higher the priority, the earlier the clause will be processed.
aliases => \@aliases OR $alias
Define aliases. Optional.
code => $code
Optional. Define implementation for the clause. The code will be installed as 'clause_$name'.
into => $package
By default it is the caller package, but can be set to other package.
Example:
has_clause minimum => (arg => 'int*', aliases => 'min');
Specify that clause named ALIAS is an alias for TARGET.
You have to define TARGET clause first (see has_clause above).
has_clause max_length => ...; has_clause_alias max_length => "max_len";
Define a Sah function. Used in function set roles (Data::Sah::FuncSet::*). Internally it adds a Moo requires for func_$name.
func_$name
args => [$schema_arg0, $schema_arg1, ...]
Declare schema for arguments.
Optional. Declare aliases.
Supply implementation for the function. The code will be installed as 'func_$name'.
has_func abs => (args => 'num');
Specify that function named ALIAS is an alias for TARGET.
You have to specify TARGET function first (see has_func above).
has_func_alias 'atan' => 'arctan';
