How to convert *error{OutOfMemory}![]u8 to *[]u8

seems impossible tbf

Trying to pass an allocated var into a function

[formal matrix]

how did you get a *error{OutOfMemory}![]u8 in the first place? - this is quite an odd type

[potent widget]

But it says I can't index errorOutofMemory

[finite valve]

try allocator.alloc

[potent widget]

oh

mb

thanks

[formal matrix]

also, should output be a *[]u8? - that's a double pointer...

[potent widget]

Hmmmm

not sure

[formal matrix]

it might be that you need only accept a []u8

[potent widget]

Ok

[potent widget]

but I want to change the variable output in the function

Oh

[]u8 is different from []const u8

[finite valve]

do you want to change the bytes stored in the location it points to? or do you want to make it point to a different location?

[potent widget]

point to a different location

[finite valve]

then *[]u8 or *[]const u8 is correct

[potent widget]

kk thx

[potent widget]

what again is the difference between this two?

[finite valve]

the first one lets you write to the u8s it points to, the second one doesn't

[potent widget]

wait mb, I want to change the bytes stored in the location it points

[finite valve]

oh then you probably just want []u8
