Type Mismatch Error When Comparing u32 Values Using equals in WGSL

Hey,
I’m trying to compare two u32 values using the equals function in TSL with the following WGSL code:
WGSLconst start = uint(0).toVar(); const plus = uint(0x2b); const firstCharCode = src.element(start); If(equals(firstCharCode, plus), () => { // Here start.assign(start.add(1)); })
However, I'm encountering this error:
Error while parsing WGSL: :156:24 error: type mismatch for argument 1 in call to ‘tsl_equals_bool’, expected ‘bool’, got ‘u32’
if ( tsl_equals_bool( NodeBuffer_558.value[ nodeVar3 ].x, 43u ) ) {
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I searched for a tsl_equals_u32 WGSL function on GitHub (see links below), but couldn't find one.
Does this mean that the equals function cannot be used with u32, f32, or i32 types, or did I miss something? Any guidance would be appreciated!

TSL Comparison for u32 Values
You're encountering an error because the equals function in TSL appears to be specifically designed for boolean comparisons, not for numeric types like u32.
For comparing numeric values in TSL/WGSL, you should use the standard equality operator (==) instead of the equals function. Here's how you can fix your code:
WGSLconst start = uint(0).toVar(); const plus = uint(0x2b); const firstCharCode = src.element(start); If(firstCharCode == plus, () => { // Use == instead of equals() start.assign(start.add(1)); })
The error message indicates that tsl_equals_bool expects boolean arguments, but you're providing a u32 value. This suggests that the equals function is specifically for boolean equality checks, not for comparing numeric types.
When working with numeric types in WGSL/TSL, use the standard comparison operators (==, !=, <, >, <=, >=) for your comparisons.
